Name of the Vulnerable Software and Affected Versions:

Freeware Advanced Audio Decoder 2 (FAAD2) version 2.8.8

Description:

The issue is related to an invalid memory address dereference in the `lt prediction` function, which can cause a segmentation fault and application crash, leading to denial of service. This is due to a buffer overflow error, allowing an attacker to potentially cause a denial of service.

Recommendations:

For Freeware Advanced Audio Decoder 2 (FAAD2) version 2.8.8, consider disabling the `lt prediction` function as a temporary workaround until a patch is available. Restrict access to the affected `lt predict.c` module to minimize the risk of exploitation.
