{"id":"OESA-2026-3604","summary":"libmodplug security update","details":"The library which was part of the Modplug-xmms project.\r\n\r\nSecurity Fix(es):\n\nlibmodplug through 0.8.9.1 contains an out-of-bounds read in pat_smplooped in src/load_pat.cpp. The function validates only the upper bound of its sample index against MAXSMP and then subtracts one before indexing the 191-byte static array pat_loops, so an index of zero reads pat_loops[-1], one byte before the array. The index is the smpno field of a parsed MIDI event, which is initialised to zero and only later overwritten from a program-change parameter, so an event reaching the note test before an instrument is assigned carries zero. A 32-byte MIDI file supplied to the library's public ModPlug_Load entry point drives the path through CSoundFile::Create, CSoundFile::ReadMID, and MID_ReadPatterns to the read. The byte read out of bounds determines whether a note event is treated as looping, so adjacent static storage influences playback state.(CVE-2026-75904)","modified":"2026-09-05T15:16:25.278238660Z","published":"2026-09-05T15:03:04Z","upstream":["CVE-2026-75904"],"database_specific":{"severity":"Low"},"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3604"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-75904"}],"affected":[{"package":{"name":"libmodplug","ecosystem":"openEuler:22.03-LTS-SP4","purl":"pkg:rpm/openEuler/libmodplug&distro=openEuler-22.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.8.9.0-11.oe2203sp4"}]}],"ecosystem_specific":{"aarch64":["libmodplug-0.8.9.0-11.oe2203sp4.aarch64.rpm","libmodplug-debuginfo-0.8.9.0-11.oe2203sp4.aarch64.rpm","libmodplug-debugsource-0.8.9.0-11.oe2203sp4.aarch64.rpm","libmodplug-devel-0.8.9.0-11.oe2203sp4.aarch64.rpm"],"src":["libmodplug-0.8.9.0-11.oe2203sp4.src.rpm"],"x86_64":["libmodplug-0.8.9.0-11.oe2203sp4.x86_64.rpm","libmodplug-debuginfo-0.8.9.0-11.oe2203sp4.x86_64.rpm","libmodplug-debugsource-0.8.9.0-11.oe2203sp4.x86_64.rpm","libmodplug-devel-0.8.9.0-11.oe2203sp4.x86_64.rpm"]},"database_specific":{"source":"https://repo.openeuler.org/security/data/osv/OESA-2026-3604.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"}]}
