Name of the Vulnerable Software and Affected Versions HE-AAC+ Codec (aka libaacplus) version 2.0.2

Description The issue is related to a left-shift undefined behavior in the au channel.h file, which could allow remote attackers to cause a denial of service, potentially leading to an application crash, or possibly having other unspecified impacts. This can be achieved via a crafted audio file.

Recommendations For HE-AAC+ Codec (aka libaacplus) version 2.0.2, consider avoiding the use of crafted audio files that could trigger the left-shift undefined behavior issue until a patch or fix is available.
