Details

A NULL pointer dereference was discovered in ifilterbank 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 LONGSTART_SEQUENCE case.
