Thursday, July 19, 2018 08:28 These vulnerabilities were discovered by Tyler Bohan of Cisco TalosToday, Talos is disclosing several vulnerabilities that have been identified in Canvas Draw graphics editing tool for Macs.Canvas Draw 4 is a graphics editing tool used to create and edit images, as well as other graphic-related material. This product has a large user base, and is popular in its specific field. The vulnerable component is in the handling of TIFF images. TIFF is a raster-based image format used in graphics editing projects, thus making it a very common file format for such an application.Vulnerability Details TALOS-2018-0541 (CVE-2018-3857) - ACD Systems Canvas Draw 4 setRasterData Heap Overflow Code Execution Vulnerability TALOS-2018-0541 describes an exploitable heap overflow vulnerability that exists in the TIFF parsing functionality of Canvas Draw version 4.0.0. A specially crafted TIFF image processed via the application can lead to an out-of-bounds write, overwriting arbitrary data. An attacker can deliver a TIFF image to trigger this vulnerability and gain code execution.The vulnerability arises in the parsing of a compressed and tiled TIFF image. TIFF has support for multiple versions of image compression, and an image application is expected to be able to handle them. The tag used to define levels of compression is tag number 259. The crash happens due to an invalid object being freed on the free list.TALOS-2018-0542 (CVE-2018-3858) - ACD Systems Canvas Draw 4 PlanarConfiguration Heap Overflow Code Execution Vulnerability TALOS-2018-0542 is an exploitable heap overflow vulnerability that exists in the TIFF parsing functionality of Canvas Draw version 4.0.0.

Can lead to an out of bounds write overwriting arbitrary data. An attacker can deliver a TIFF image to trigger this vulnerability and gain code execution.The vulnerability arises in the parsing of a tiled TIFF image with the Adobe Deflate compression scheme. This compression algorithm is not part of the TIFF standard algorithms but was added as an extension from Adobe and uses a lossless Deflate compression scheme utilizing the zlib compressed data format. The Canvas Draw application supports this compression format and is able to handle files using it. The vulnerability arises in attempting to build a Huffman table.TALOS-2018-0544 (CVE-2018-3860) - ACD Systems Canvas Draw 4 Resoultion_Set Out of Bounds Write Code Execution Vulnerability TALOS-2018-0544 is an exploitable out of bounds write vulnerability that exists in the TIFF parsing functionality of Canvas Draw version 4.0.0.

Restore 方法比手动恢复原先的状态要简单得多。又如果你是在一个循环中做位移但没有保存和恢复 canvas 的状态，很可能到最后会发现怎么有些东西不见了，那是因为它很可能已经超出 canvas 范围以外了。​ 注意：translate 移动的是 canvas 的坐标原点(坐标变换)。var ctx;function draw(){ var canvas = document.getElementById('tutorial1'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.save(); ctx.translate(100, 100); ctx.strokeRect(0, 0, 100, 100) ctx.restore(); ctx.translate(220, 220); ctx.fillRect(0, 0, 100, 100)}draw();9.2 rotaterotate(angle)​ 旋转坐标轴。​ 这个方法只接受一个参数：旋转的角度(angle)，它是顺时针方向的，以弧度为单位的值。​ 旋转的中心是坐标原点。var ctx;function draw(){ var canvas = document.getElementById('tutorial1'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.fillStyle = "red"; ctx.save(); ctx.translate(100, 100); ctx.rotate(Math.PI / 180 * 45); ctx.fillStyle = "blue"; ctx.fillRect(0, 0, 100, 100); ctx.restore(); ctx.save(); ctx.translate(0, 0); ctx.fillRect(0, 0, 50, 50) ctx.restore();}draw();9.3 scalescale(x, y)我们用它来增减图形在 canvas 中的像素数目，对形状，位图进行缩小或者放大。scale方法接受两个参数。x,y 分别是横轴和纵轴的缩放因子，它们都必须是正值。值比 1.0 小表示缩 小，比 1.0 大则表示放大，值为 1.0 时什么效果都没有。​ 默认情况下，canvas 的 1 单位就是 1 个像素。举例说，如果我们设置缩放因子是 0.5，1 个单位就变成对应 0.5 个像素，这样绘制出来的形状就会是原先的一半。同理，设置为 2.0 时，1 个单位就对应变成了 2 像素，绘制的结果就是图形放大了 2 倍。9.4 transform (变形矩阵)transform(a, b, c, d, e, f)a (m11): Horizontal scaling.b (m12): Horizontal skewing.c (m21):​ Vertical skewing.d (m22):​ Vertical scaling.e (dx):​ Horizontal moving.f (dy):​ Vertical moving.var ctx;function draw(){ var canvas = document.getElementById('tutorial1'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.transform(1, 1, 0, 1, 0, 0); ctx.fillRect(0, 0, 100, 100);}draw();十、合成​ 在前面的所有例子中、，我们总是将一个图形画在另一个之上，对于其他更多的情况，仅仅这样是远远不够的。比如，对合成的图形来说，绘制顺序会有限制。不过，我们可以利用 globalCompositeOperation 属性来改变这种状况。globalCompositeOperation = typevar ctx;function draw(){ var canvas = document.getElementById('tutorial1'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.fillStyle = "blue"; ctx.fillRect(0, 0, 200, 200); ctx.globalCompositeOperation = "source-over"; ctx.fillStyle = "red"; ctx.fillRect(100, 100, 200, 200);}draw();注：下面的展示中，蓝色是原有的，红色是新的。type 是下面 13 种字符串值之一：1、这是默认设置，新图像会覆盖在原有图像。2. source-in仅仅会出现新图像与原来图像重叠的部分，其他区域都变成透明的。(包括其他的老图像区域也会透明)3. source-out仅仅显示新图像与老图像没有重叠的部分，其余部分全部透明。(老图像也不显示)4. source-atop新图像仅仅显示与老图像重叠区域。老图像仍然可以显示。5. destination-over新图像会在老图像的下面。6. destination-in仅仅新老图像重叠部分的老图像被显示，其他区域全部透明。7. destination-out仅仅老图像与新图像没有重叠的部分。 注意显示的是老图像的部分区域。8. destination-atop老图像仅仅仅仅显示重叠部分，新图像会显示在老图像的下面。9. lighter新老图像都显示，但是重叠区域的颜色做加处理。10. darken保留重叠部分最黑的像素。(每个颜色位进行比较，得到最小的)blue: #0000ffred: #ff0000所以重叠部分的颜色：#000000。11. lighten保证重叠部分最量的像素。(每个颜色位进行比较，得到最大的)blue: #0000ffred: #ff0000所以重叠部分的颜色：#ff00ff。12. xor重叠部分会变成透明。13. copy只有新图像会被保留，其余的全部被清除(边透明)。十一、裁剪路径clip()​ 把已经创建的路径转换成裁剪路径。​ 裁剪路径的作用是遮罩。只显示裁剪路径内的区域，裁剪路径外的区域会被隐藏。​ 注意：clip() 只能遮罩在这个方法调用之后绘制的图像，如果是 clip() 方法调用之前绘制的图像，则无法实现遮罩。var ctx;function draw(){ var canvas = document.getElementById('tutorial1'); if (!canvas.getContext) return; var ctx = canvas.getContext("2d"); ctx.beginPath(); ctx.arc(20,20, 100, 0, Math.PI * 2); ctx.clip(); ctx.fillStyle = "pink"; ctx.fillRect(20, 20, 100,100);}draw();十二、动画动画的基本步骤清空 canvas 再绘制每一帧动画之前，需要清空所有。清空所有最简单的做法就是 clearRect() 方法。保存 canvas 状态 如果在绘制的过程中会更改 canvas 的状态(颜色、移动了坐标原点等),又在绘制每一帧时都是原始状态的话，则最好保存下 canvas 的状态绘制动画图形这一步才是真正的绘制动画帧恢复 canvas 状态如果你前面保存了 canvas 状态，则应该在绘制完成一帧之后恢复 canvas 状态。控制动画我们可用通过 canvas 的方法或者自定义的方法把图像会知道到 canvas 上。正常情况，我们能看到绘制的结果是在脚本执行结束之后。例如，我们不可能在一个 for 循环内部完成动画。也就是，为了执行动画，我们需要一些可以定时执行重绘的方法。一般用到下面三个方法：setInterval()setTimeout()requestAnimationFrame()案例1：太阳系let sun;let earth;let moon;let ctx;function init(){ sun = new Image(); earth = new Image(); moon = new Image(); sun.src = "sun.png"; earth.src = "earth.png"; moon.src = "moon.png"; let canvas = document.querySelector("#solar"); ctx = canvas.getContext("2d"); sun.onload = function (){ draw() } }init();function draw(){ ctx.clearRect(0, 0, 300, 300); ctx.drawImage(sun, 0, 0, 300, 300); ctx.save(); ctx.translate(150, 150); ctx.beginPath(); ctx.strokeStyle = "rgba(255,255,0,0.5)"; ctx.arc(0, 0, 100, 0, 2 * Math.PI) ctx.stroke() let time = new Date(); ctx.rotate(2 * Math.PI / 60 * time.getSeconds() + 2 * Math.PI / 60000 * time.getMilliseconds()) ctx.translate(100, 0); ctx.drawImage(earth, -12, -12) ctx.beginPath(); ctx.strokeStyle = "rgba(255,255,255,.3)"; ctx.arc(0, 0, 40, 0, 2 * Math.PI); ctx.stroke(); ctx.rotate(2 * Math.PI / 6 * time.getSeconds() + 2 * Math.PI / 6000 * time.getMilliseconds()); ctx.translate(40, 0); ctx.drawImage(moon, -3.5, -3.5); ctx.restore(); requestAnimationFrame(draw);}案例2：模拟时钟init(); function init(){ let canvas = document.querySelector("#solar"); let.

An exploitable out of bounds write vulnerability that exists in the PCX parsing functionality of Canvas Draw version 4.0.0. A specially crafted PCX image processed via the application can lead to an out of bounds write overwriting arbitrary data. An attacker can deliver a PCX image to trigger this vulnerability and gain code execution.The vulnerability arises in parsing the PCX image, specifically dealing with the column and row sizes of the image. Inside of the PCX header, values are set to determine the location of image data and the size of the image itself. By passing in incorrect values the application will write out of bounds attempting to access the image data.Affected versions The vulnerabilities are confirmed in the Canvas Draw version 4.0.0 but they may also be present in the earlier versions of the product. Users are advised to apply the latest security update for their version.The complexity of image file formats means that there is a lot of scope for vulnerabilities to be inadvertently included in programs that parse them. Organizations need to remain abreast of vulnerabilities in the image editing software packages such as ACD Systems Canvas Draw and update to the latest version as soon as possible.Coverage The following Snort Rules detect attempts to exploit these vulnerabilities. Please note that additional rules may be released at a future date and current rules are subject to change pending additional vulnerability information.

DeltaTime = timestamp - lastTimestamp; lastTimestamp = timestamp; // Update game state based on time passed updateGameLogic(deltaTime); // Render the current frame renderFrame(); // Schedule the next frame requestAnimationFrame(gameLoop);}// Start the looprequestAnimationFrame(gameLoop);This pattern works well with both HTML5 Canvas and WebGL rendering approaches.Key Components of an Effective Game LoopUpdating the Game StateHandling movement, physics, and AI logicThe update function manages all dynamic aspects of your game:function updateGameState(deltaTime) { updatePlayerPosition(deltaTime); updateEnemyAI(deltaTime); simulatePhysics(deltaTime); checkCollisions(); processGameEvents();}For complex physics, consider libraries integrated with your chosen game engine:Phaser uses its own physics systemThree.js can integrate with physics librariesCustom solutions need careful time-step managementDifferent physics systems (arcade, realistic) require different update approaches.Ensuring consistency in game logic updatesConsistency matters more than raw speed. Your game mechanics should behave predictably regardless of frame rate fluctuations.Time-based movement is critical:// Bad: Frame-dependent movementplayer.x += 5; // Moves 5px every frame// Good: Time-based movementplayer.x += 300 * deltaTime; // Moves 300px per secondThis approach ensures game state management remains consistent across devices with different performance levels.Rendering the Game FrameRedrawing game elements on the canvas or DOMRendering transforms your game state into visible output:function renderFrame() { // Clear the canvas ctx.clearRect(0, 0, canvas.width, canvas.height); // Draw background renderBackground(); // Draw game objects renderEntities(); // Draw UI elements renderInterface();}Modern browser rendering engines optimize for canvas operations, but DOM manipulation can be expensive.Consider these approaches based on game type:2D sprite-based games: Canvas API3D games: WebGLUI-heavy games: Combination of Canvas and limited DOMAvoiding unnecessary rendering for performance optimizationSmart rendering saves processing power:Only redraw elements that changedUse layers for static elementsImplement object culling (don’t render off-screen)Batch similar drawing operationsIndie game development often benefits from these optimization techniques when targeting mobile browsers.Managing Timing and Delta TimeUnderstanding delta time for smooth animationsDelta time represents the milliseconds elapsed since the last frame:function update(deltaTime) { // deltaTime is in milliseconds (e.g., 16.67ms at 60fps) // Convert to seconds for easier math const deltaSeconds = deltaTime / 1000; // Move at 100 pixels per second regardless of frame rate player.x += 100 * deltaSeconds;}This approach ensures animation smoothness even when frame rates drop.The ECMAScript timing functions, combined with requestAnimationFrame, provide precise measurement tools.Ensuring time-based updates rather than frame-based updatesFrame-based updates create inconsistent gameplay experiences. A jump might reach different heights depending on the device’s performance.Time-based systems fix this:// Frame-based (problematic)function updateJump() { if (jumping) { player.y -= jumpSpeed; jumpSpeed -= gravity; }}// Time-based (consistent)function updateJump(deltaTime) { if (jumping) { player.y -=.
