CVE-2013-4234

An integer overflow within the "abc_set_parts()" function (src/load_abc.cpp) can be exploited to corrupt heap memory via a specially crafted ABC file (CVE-2013-4233).

An error within the "abc_MIDI_drum()" and "abc_MIDI_gchord()" functions (src/load_abc.cpp) can be exploited to cause a buffer overflow via a specially crafted ABC file (CVE-2013-4234).

These are all security issues fixed in the libmodplug-devel-0.8.8.5-4.9 package on the GA media of openSUSE Tumbleweed.

This update for libmodplug fixes the following issues:

• Update to version 0.8.9.0+git20170610.f6dd59a bsc#1022032:

  • PSM: add missing line to commit
  • ABC: prevent possible increment of p past end
  • ABC: ensure read pointer is valid before incrementing
  • ABC: terminate early when things don't work in substitute
  • OKT: add one more bound check
  • FAR: out by one on check
  • ABC: 10 digit ints require null termination
  • PSM: make sure reads occur of only valid ins
  • ABC: cleanup tracks correctly.
  • WAV: check that there is space for both headers
  • OKT: ensure file size is enough to contain data
  • ABC: initialize earlier
  • ABC: ensure array access is bounded correctly.
  • ABC: clean up loop exiting code
  • ABC: avoid possibility of incrementing *p
  • ABC: abort early if macro would be blank
  • ABC: Use blankline more often
  • ABC: Ensure for loop does not increment past end of loop
  • Initialize nPatterns to 0 earlier
  • Check memory position isn't over the memory length
  • ABC: transpose only needs to look at notes (<26)

• Update to version 0.8.9.0+git20171024.e9fc46e:

  • Spelling fixes
  • Bump version number to 0.8.9.0
  • MMCMP: Check that end pointer is within the file size
  • WAV: ensure integer doesn't overflow
  • XM: additional mempos check
  • sndmix: Don't process row if its empty.
  • snd_fx: dont include patterns of zero size in length calc
  • MT2,AMF: prevent OOB reads

• Add patch for broken pc file where quite some upstream refer to modplug directly without specifying the subdir it is in.

• Update to version 0.8.8.5

  • Some security issues: CVE-2013-4233, CVE-2013-4234, as well as many fixes suggested by static analyzers: clang build-scan, and coverity.

Multiple heap-based buffer overflows in the (1) abc_MIDI_drum and (2) abc_MIDI_gchord functions in load_abc.cpp in libmodplug 0.8.8.4 and earlier allow remote attackers to cause a denial of service (memory corruption and crash) and possibly execute arbitrary code via a crafted ABC.
