{"id":"UBUNTU-CVE-2026-111156","details":"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.","modified":"2026-10-17T12:58:04.173376184Z","published":"2026-10-16T00:00:00Z","upstream":["CVE-2026-111156"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-111156"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-111156"},{"type":"REPORT","url":"https://github.com/sezero/libtimidity"},{"type":"REPORT","url":"https://github.com/sezero/libtimidity/blob/a52adf6aee2635e2a16797213a089c2180e67757/src/sndfont.c#L199-L224"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/libtimidity-soundfont-generator-oper-oob-write"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/libtimidity-through-0.2.8-out-of-bounds-access-via-soundfont-preset-header"}],"affected":[{"package":{"name":"timidity","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/timidity?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.13.2-40.2build1","2.13.2-40.3"],"ecosystem_specific":{"binaries":[{"binary_name":"timidity","binary_version":"2.13.2-40.3"},{"binary_name":"timidity-daemon","binary_version":"2.13.2-40.3"},{"binary_name":"timidity-el","binary_version":"2.13.2-40.3"},{"binary_name":"timidity-interfaces-extra","binary_version":"2.13.2-40.3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111156.json"}},{"package":{"name":"timidity","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/timidity?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.13.2-40.5","2.13.2-41"],"ecosystem_specific":{"binaries":[{"binary_name":"timidity","binary_version":"2.13.2-41"},{"binary_name":"timidity-daemon","binary_version":"2.13.2-41"},{"binary_name":"timidity-el","binary_version":"2.13.2-41"},{"binary_name":"timidity-interfaces-extra","binary_version":"2.13.2-41"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111156.json"}},{"package":{"name":"timidity","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/timidity?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.0-8build1"],"ecosystem_specific":{"binaries":[{"binary_name":"timidity","binary_version":"2.14.0-8build1"},{"binary_name":"timidity-daemon","binary_version":"2.14.0-8build1"},{"binary_name":"timidity-el","binary_version":"2.14.0-8build1"},{"binary_name":"timidity-interfaces-extra","binary_version":"2.14.0-8build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111156.json"}},{"package":{"name":"timidity","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/timidity?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.0-8build1","2.14.0-8ubuntu1","2.14.0-8ubuntu1.22.04.1"],"ecosystem_specific":{"binaries":[{"binary_name":"timidity","binary_version":"2.14.0-8ubuntu1.22.04.1"},{"binary_version":"2.14.0-8ubuntu1.22.04.1","binary_name":"timidity-daemon"},{"binary_version":"2.14.0-8ubuntu1.22.04.1","binary_name":"timidity-el"},{"binary_name":"timidity-interfaces-extra","binary_version":"2.14.0-8ubuntu1.22.04.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111156.json"}},{"package":{"name":"timidity","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/timidity?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.0-8.1ubuntu1","2.14.0-8.1ubuntu4","2.14.0-8.2ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"timidity","binary_version":"2.14.0-8.2ubuntu1"},{"binary_name":"timidity-daemon","binary_version":"2.14.0-8.2ubuntu1"},{"binary_name":"timidity-el","binary_version":"2.14.0-8.2ubuntu1"},{"binary_version":"2.14.0-8.2ubuntu1","binary_name":"timidity-interfaces-extra"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111156.json"}},{"package":{"name":"timidity","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/timidity?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.0-8.3ubuntu1","2.14.0-8.4ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"timidity","binary_version":"2.14.0-8.4ubuntu1"},{"binary_name":"timidity-el","binary_version":"2.14.0-8.4ubuntu1"},{"binary_name":"timidity-interfaces-extra","binary_version":"2.14.0-8.4ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111156.json"}},{"package":{"name":"timidity","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/timidity?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.14.0-8.3ubuntu1"],"ecosystem_speci
