Description

An issue was discovered in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. The faad_resetbits function in libfaad/bits.c is affected by a buffer overflow vulnerability. The number of bits to be read is determined by ld-buffer_size - words4 cast to uint32. If ld-buffer_size - words4 is negative a buffer overflow is later performed via getdword_n(&ld-start[words] ld-bytes_left).
