From URL: vorbis-tools oggenc vulnerability ================ Author : qflb.wu =============== Introduction: ============= The Vorbis Tools package contains command-line tools useful for encoding, playing or editing files using the Ogg CODEC. Affected version: ===== 1.4.0 Vulnerability Description: ========================== the wav_open function in oggenc/audio.c in vorbis-tools 1.4.0 can cause a denial of service(memory allocation error) via a crafted wav file. ./oggenc vorbis-tools_1.4.0_oggenc_memory_allocation_error.wav -o out ==68126==WARNING: AddressSanitizer failed to allocate 0xffffffffffffbc00 bytes ==68126==AddressSanitizer's allocator is terminating the process instead of returning 0 ==68126==If you don't like this behavior set allocator_may_return_null=1 ==68126==AddressSanitizer CHECK failed: /build/buildd/llvm-toolchain-3.4-3.4/projects/compiler-rt/lib/sanitizer_common/sanitizer_allocator.cc:149 "((0)) != (0)" (0x0, 0x0) #0 0x46d41f in __asan::AsanCheckFailed(char const*, int, char const*, unsigned long long, unsigned long long) (/home/a/Downloads/vorbis-tools-1.4.0/oggenc/oggenc+0x46d41f) #1 0x472c81 in __sanitizer::CheckFailed(char const*, int, char const*, unsigned long long, unsigned long long) (/home/a/Downloads/vorbis-tools-1.4.0/oggenc/oggenc+0x472c81) #2 0x4719c0 in __sanitizer::AllocatorReturnNull() (/home/a/Downloads/vorbis-tools-1.4.0/oggenc/oggenc+0x4719c0) #3 0x4674b6 in __interceptor_malloc (/home/a/Downloads/vorbis-tools-1.4.0/oggenc/oggenc+0x4674b6) #4 0x492896 in wav_open /home/a/Downloads/vorbis-tools-1.4.0/oggenc/audio.c:573 #5 0x496d8e in open_audio_file /home/a/Downloads/vorbis-tools-1.4.0/oggenc/audio.c:86 #6 0x485d0a in main /home/a/Downloads/vorbis-tools-1.4.0/oggenc/oggenc.c:256 #7 0x7f6d9f8dcec4 (/lib/x86_64-linux-gnu/libc.so.6+0x21ec4) #8 0x47d55c in _start (/home/a/Downloads/vorbis-tools-1.4.0/oggenc/oggenc+0x47d55c) ----------------- wav->channel_permute = malloc(wav->channels * sizeof(int)); if (wav->channels <= 8) /* Where we know the mappings, use them. */ memcpy(wav->channel_permute, wav_permute_matrix[wav->channels-1], sizeof(int) * wav->channels); else /* Use a default 1-1 mapping */ for (i=0; i < wav->channels; i++) wav->channel_permute[i] = i; return 1; Andthe code didn't check the return of malloc.
This is supposedly fixed by bug 537422 already. https://security-tracker.debian.org/tracker/CVE-2017-11331
sound done here as well.
tree is clean.
