Vulnerabilities

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 - words*4, cast to uint32. If ld->buffer_size - words*4 is negative, a buffer overflow is later performed via getdword_n(&ld->start[words], ld->bytes_left).

An issue was discovered in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. It is a buffer over-read in ps_mix_phase in libfaad/ps_dec.c.

An invalid memory address dereference was discovered in the hf_assembly function of libfaad/sbr_hfadj.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.

There is a stack-based buffer underflow in the third instance of the calculate_gain function in libfaad/sbr_hfadj.c in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. A crafted input will lead to a denial of service or possibly unspecified other impact because limiting the additional noise energy level is mishandled for the G_max <= G case.

An invalid memory address dereference was discovered in the huffcode function (libfaac/huff2.c) in Freeware Advanced Audio Coder (FAAC) 1.29.9.2. The vulnerability causes a segmentation fault and application crash, which leads to denial of service in the book 8 case.

An issue was discovered in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.1. There was a heap-based buffer overflow in the function excluded_channels() in libfaad/syntax.c.

The mp4ff_read_ctts function in common/mp4ff/mp4atom.c in Freeware Advanced Audio Decoder 2 (FAAD2) 2.7 allows remote attackers to cause a denial of service (large loop and CPU consumption) via a crafted mp4 file.

The wav_open_read function in frontend/input.c in Freeware Advanced Audio Coder (FAAC) 1.28 allows remote attackers to cause a denial of service (large loop) via a crafted wav file.
