Detailsinfo

A vulnerability classified as critical was found in Google Chrome up to 23.0.1271.96 (Web Browser). Affected by this vulnerability is an unknown code of the component AAC Decoding Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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."

The bug was discovered 12/11/2012. The weakness was published 12/11/2012 by Chamal De Silva (pawlkt) with Google Chrome Security Team as confirmed changelog entry (Website).
