--- title: "CVE-2014-8541\n | Ubuntu" description: Ubuntu is an open source software operating system that runs from the desktop, to the cloud, to all your internet connected things. url: https://ubuntu.com/security/CVE-2014-8541?format=md keywords: index, follow --- # CVE-2014-8541 Publication date 5 November 2014 Last updated 24 July 2024 --- Ubuntu priority **Low** [Why this priority?](https://ubuntu.com/security/cves/about#priority ) Toggle side navigation ## Description libavcodec/mjpegdec.c in FFmpeg before 2.4.2 considers only dimension differences, and not bits-per-pixel differences, when determining whether an image size has changed, which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted MJPEG data. ### From the Ubuntu Security Team It was discovered that Libav incorrectly handled certain media files. An attacker could possibly use this issue to cause a denial of service or other unspecified impact. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | ffmpeg | 19.04 disco | Not affected | | 18.10 cosmic | Not affected | | 18.04 LTS bionic | Not affected | | 17.10 artful | Not affected | | 17.04 zesty | Not affected | | 16.10 yakkety | Not affected | | 16.04 LTS xenial | Not affected | | 15.10 wily | Not affected | | 15.04 vivid | Not affected | | 14.10 utopic | Not in release | | 14.04 LTS trusty | Not in release | | 12.04 LTS precise | Not in release | | 10.04 LTS lucid | Ignored end of life | | libav | 19.04 disco | Not in release | | 18.10 cosmic | Not in release | | 18.04 LTS bionic | Not in release | | 17.10 artful | Not in release | | 17.04 zesty | Not in release | | 16.10 yakkety | Not in release | | 16.04 LTS xenial | Not in release | | 15.10 wily | Not in release | | 15.04 vivid | Not affected | | 14.10 utopic | Ignored end of life | | 14.04 LTS trusty | Fixed 6:9.20-0ubuntu0.14.04.1+esm1 Ubuntu Pro | | 12.04 LTS precise | Fixed 4:0.8.17-0ubuntu0.12.04.2 | | 10.04 LTS lucid | Not in release | | mplayer | 19.04 disco | Not affected | | 18.10 cosmic | Not affected | | 18.04 LTS bionic | Not affected | | 17.10 artful | Ignored end of life | | 17.04 zesty | Ignored end of life | | 16.10 yakkety | Ignored end of life | | 16.04 LTS xenial | Not affected | | 15.10 wily | Not in release | | 15.04 vivid | Not in release | | 14.10 utopic | Not in release | | 14.04 LTS trusty | Not in release | | 12.04 LTS precise | Ignored end of life | | 10.04 LTS lucid | Ignored end of life | --- * [How can I get the fixes?](https://ubuntu.com/security/cves/about#security) * [What do statuses mean?](https://ubuntu.com/security/cves/about#statuses) * [Patch details](https://ubuntu.com/security/CVE-2014-8541?format=md#patch-details) ### Get expanded security coverage with Ubuntu Pro Reduce your average CVE exposure time from 98 days to 1 day with expanded CVE patching, ten-years security maintenance and optional support for the full stack of open-source applications.
