Vetor base

AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions: Libav version 12.2

Description: The issue allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted aac file. This is due to a problem in the apply dependent coupling function in libavcodec/aacdec.c.

Recommendations: For Libav version 12.2, consider disabling the apply dependent coupling function as a temporary workaround until a patch is available. Restrict access to crafted aac files to minimize the risk of exploitation.
