NVD Description

Note: Versions mentioned in the description apply only to the upstream faad2 package and not the faad2 package as distributed by Alpine. See How to fix? for Alpine:3.13 relevant fixed versions and status.

A NULL pointer dereference was discovered in ifilter_bank of libfaad/filtbank.c in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. The vulnerability causes a segmentation fault and application crash, which leads to denial of service because adding to windowed output is mishandled in the ONLY_LONG_SEQUENCE case.
