Attackers can craft a GIF whose frame left plus width exceeds the logical screen width, causing GifPlaybackCompositeFrame() and GifPlaybackFillRect() to corrupt heap memory when loaded with GIF_PLAYBACK.","cvssScore":7.8,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://github.com/danoli3/FreeImage","tags":[]},{"url":"https://github.com/danoli3/FreeImage/blob/3.19.24/Source/FreeImage/PluginGIF.cpp#L719-L772","tags":[]},{"url":"https://github.com/danoli3/FreeImage/commit/0da5ddb4d311e5222251348cca1aa988478b1034","tags":[]},{"url":"https://github.com/danoli3/FreeImage/commit/96f4099f8e307484ba69b4aa14d772b7679a1bfb","tags":[]},{"url":"https://github.com/danoli3/FreeImage/pull/183","tags":[]},{"url":"https://github.com/danoli3/FreeImage/releases/tag/3.19.25","tags":[]},{"url":"https://www.vulncheck.com/advisories/freeimage-danoli3-fork-before-3.19.25-heap-buffer-overflow-via-gif-playback-compositing","tags":[]}],"exploitRefs":[{"url":"https://github.com/danoli3/FreeImage","tags":[]},{"url":"https://github.com/danoli3/FreeImage/blob/3.19.24/Source/FreeImage/PluginGIF.cpp#L719-L772","tags":[]},{"url":"https://github.com/danoli3/FreeImage/commit/0da5ddb4d311e5222251348cca1aa988478b1034","tags":[]},{"url":"https://github.com/danoli3/FreeImage/commit/96f4099f8e307484ba69b4aa14d772b7679a1bfb","tags":[]},{"url":"https://github.com/danoli3/FreeImage/pull/183","tags":[]},{"url":"https://github.com/danoli3/FreeImage/releases/tag/3.19.25","tags":[]}],"hasPoc":true,"ai":null}
