libTiMidity through 0.2.8 Out-of-Bounds Access via SoundFont Preset Header

libTiMidity through 0.2.8 contains an out-of-bounds access vulnerability in init_soundfont() in src/sndfont.c that allows attackers to corrupt memory by supplying unvalidated SF2 preset header bank and preset values. Attackers can craft a .sf2 file whose bank or preset indexes past the 128-entry tonebank or drumset arrays, causing heap memory reads, writes, and application crashes.

libTiMidity through 0.2.8 Out-of-Bounds Read via SoundFont Loader sndfont.c

libTiMidity through 0.2.8 contains a heap out-of-bounds read vulnerability in the SoundFont loader in src/sndfont.c that uses unvalidated sampleId and instrument generator values as table indices. Attackers can supply a crafted .sf2 file loaded through mid_set_soundfont() to read heap memory out of bounds and crash the application.

libTiMidity through 0.2.8 Stack Out-of-Bounds Write via parse_gen in SoundFont Loader

libTiMidity through 0.2.8 contains a stack out-of-bounds write vulnerability in the SoundFont loader that allows attackers to corrupt stack memory via unchecked generator operators in parse_gen. Attackers can supply a crafted .sf2 file with out-of-range pgen/igen operator values to write chosen 16-bit values near the stack Layer object, causing crashes and stack memory corruption.

CVE-2017-11549

The play_midi function in playmidi.c in TiMidity++ 2.14.0 allows remote attackers to cause a denial of service (large loop and CPU consumption) via a crafted mid file. NOTE: CPU consumption might be relevant when using the --background option.

CVE-2017-11547

The resample_gauss function in resample.c in TiMidity++ 2.14.0 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted mid file. NOTE: a crash might be relevant when using the --background option. NOTE: the TiMidity++ README.alsaseq documentation suggests a setuid-root installation.

CVE-2017-11546

The insert_note_steps function in readmidi.c in TiMidity++ 2.14.0 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted mid file. NOTE: a crash might be relevant when using the --background option.
