CVE-2018-11710

soundlib/pattern.h in libopenmpt before 0.3.9 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted AMS file because of an invalid write near address 0 in an out-of-memory situation.

These are all security issues fixed in the libopenmpt-devel-0.5.11-1.2 package on the GA media of openSUSE Tumbleweed.

This update for libopenmpt to version 0.3.9 fixes the following issues:

These security issues were fixed:

• CVE-2018-11710: Prevent write near address 0 in out-of-memory situations when reading AMS files (bsc#1095644)
• CVE-2018-10017: Preven out-of-bounds memory read with IT/ITP/MO3 files containing pattern loops (bsc#1089080)

These non-security issues were fixed:

• [Bug] openmpt123: Fixed build failure in C++17 due to use of removed feature std::random_shuffle.
• STM: Having both Bxx and Cxx commands in a pattern imported the Bxx command incorrectly.
• STM: Last character of sample name was missing.
• Speed up reading of truncated ULT files.
• ULT: Portamento import was sometimes broken.
• The resonant filter was sometimes unstable when combining low-volume samples, low cutoff and high mixing rates.
• Keep track of active SFx macro during seeking.
• The 'note cut' duplicate note action did not volume-ramp the previously playing sample.
• A song starting with non-existing patterns could not be played.
• DSM: Support restart position and 16-bit samples.
• DTM: Import global volume.

It was discovered that OpenMPT incorrectly handled certain files. A remote attacker could possibly use this issue to cause a denial of service or other unspecified impact.
