CVE-2017-13712

NULL Pointer Dereference in the id3v2AddAudioDuration function in libmp3lame/id3tag.c in LAME 3.99.5 allows attackers to perform Denial of Service by triggering a NULL first argument.

LAME 3.100 has been released including fixes to security vulnerabilities. Note the MP3 patents have expired.

This update for lame fixes the following issues:

Lame was updated to version 3.100:

• Improved detection of MPEG audio data in RIFF WAVE files. sf#3545112 Invalid sampling detection
• New switch --gain <decibel>, range -20.0 to +12.0, a more convenient way to apply Gain adjustment in decibels, than the use of --scale <factor>.
• Fix for sf#3558466 Bug in path handling
• Fix for sf#3567844 problem with Tag genre
• Fix for sf#3565659 no progress indication with pipe input
• Fix for sf#3544957 scale (empty) silent encode without warning
• Fix for sf#3580176 environment variable LAMEOPT doesn't work anymore
• Fix for sf#3608583 input file name displayed with wrong character encoding (on windows console with CP_UTF8)
• Fix dereference NULL and Buffer not NULL terminated issues. (CVE-2017-15019 bsc#1082317 CVE-2017-13712 bsc#1082399 CVE-2015-9100 bsc#1082401)
• Fix dereference of a null pointer possible in loop.
• Make sure functions with SSE instructions maintain their own properly aligned stack. Thanks to Fabian Greffrath
• Multiple Stack and Heap Corruptions from Malicious File. (CVE-2017-9872 bsc#1082391 CVE-2017-9871 bsc#1082392 CVE-2017-9870 bsc#1082393 CVE-2017-9869 bsc#1082395 CVE-2017-9411 bsc#1082397 CVE-2015-9101 bsc#1082400)
• CVE-2017-11720: Fix a division by zero vulnerability. (bsc#1082311)
• CVE-2017-9410: Fix fill_buffer_resample function in libmp3lame/util.c heap-based buffer over-read and ap (bsc#1082333)
• CVE-2017-9411: Fix fill_buffer_resample function in libmp3lame/util.c invalid memory read and application crash (bsc#1082397)
• CVE-2017-9412: FIx unpack_read_samples function in frontend/get_audio.c invalid memory read and application crash (bsc#1082340)
• Fix clip detect scale suggestion unaware of scale input value
• HIP decoder bug fixed: decoding mixed blocks of lower sample frequency Layer3 data resulted in internal buffer overflow.
• Add lame_encode_buffer_interleaved_int()
