Base vector

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

Name of the Vulnerable Software and Affected Versions: Libmad version 0.15.1b

Description: The issue is related to the mad bit skip function in the bit.c file of the Libmad MPEG audio decoder, which can cause a heap-based buffer over-read and application crash when processing a specially crafted audio file. This can allow a remote attacker to cause a denial of service.

Recommendations: For Libmad version 0.15.1b, consider avoiding the use of the mad bit skip function until a patch is available. As a temporary workaround, restrict the processing of audio files from untrusted sources to minimize the risk of exploitation.
