#VU110602 Buffer overflow in FFmpeg - CVE-2014-8541
Vulnerability identifier: #VU110602
Vulnerability risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID:
CWE-ID:
CWE-119
Exploitation vector: Network
Exploit availability: No
Vulnerable software:
FFmpeg
Universal components / Libraries /
Libraries used by multiple products
Vendor: ffmpeg.sourceforge.net
Description
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
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.
Mitigation
Install update from vendor's website.
