Name of the Vulnerable Software and Affected Versions FAAD2 versions through 2.10.0

Description The issue is related to a heap-buffer-overflow in the lt prediction function located in lt predict.c of the FAAD2 audio decoder. This allows a remote attacker to access confidential data, compromise its integrity, and cause a denial of service. The vulnerability can also lead to code execution.

Recommendations For versions through 2.10.0, consider disabling the lt prediction function as a temporary workaround until a patch is available. Restrict access to the lt predict.c component to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
