CVE-2012-5144

Publication date 12 December 2012

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

Google Chrome before 23.0.1271.97, and Libav 0.7.x before 0.7.7 and 0.8.x before 0.8.5, do not properly perform AAC decoding, which allows remote attackers to cause a denial of service (stack memory corruption) or possibly have unspecified other impact via vectors related to "an off-by-one overwrite when switching to LTP profile from MAIN."
