{"id":"UBUNTU-CVE-2026-111148","details":"libsidplayfp through 3.1.1 contains a heap out-of-bounds read vulnerability that allows attackers to crash applications by supplying a PSID/RSID file with an unchecked data offset. Attackers can set the header data offset beyond the file size, wrapping the length calculation so resolveAddrs() reads up to 64 KiB past the heap buffer.","modified":"2026-10-17T12:58:03.952683113Z","published":"2026-10-16T00:00:00Z","upstream":["CVE-2026-111148"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-111148"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-111148"},{"type":"REPORT","url":"https://github.com/libsidplayfp/libsidplayfp"},{"type":"REPORT","url":"https://github.com/libsidplayfp/libsidplayfp/blob/732fa8ec8131fc75aafc2eaea583ddcdeea2a3cc/src/sidtune/SidTuneBase.cpp#L295-L300"},{"type":"REPORT","url":"https://github.com/libsidplayfp/libsidplayfp/blob/732fa8ec8131fc75aafc2eaea583ddcdeea2a3cc/src/sidtune/SidTuneBase.cpp#L488-L500"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/libsidplayfp-psid-dataoffset-underflow-oob-read"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/libsidplayfp-through-3.1.1-heap-out-of-bounds-read-via-sidtunebase-acceptsidtune"}],"affected":[{"package":{"name":"libsidplayfp","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libsidplayfp?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.1-1","1.8.2-1","1.8.3-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.8.3-1","binary_name":"libsidplayfp4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111148.json"}},{"package":{"name":"libsidplayfp","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libsidplayfp?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.7-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsidplayfp4","binary_version":"1.8.7-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111148.json"}},{"package":{"name":"libsidplayfp","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libsidplayfp?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.8.8-1","1.8.8-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsidplayfp4","binary_version":"1.8.8-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111148.json"}},{"package":{"name":"libsidplayfp","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libsidplayfp?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.2-1","2.3.0-2","2.3.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsidplayfp6","binary_version":"2.3.1-1"},{"binary_name":"libstilview0","binary_version":"2.3.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111148.json"}},{"package":{"name":"libsidplayfp","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libsidplayfp?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.0-1","2.5.1-1","2.6.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsidplayfp6","binary_version":"2.6.0-1"},{"binary_name":"libstilview0","binary_version":"2.6.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111148.json"}},{"package":{"name":"libsidplayfp","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/libsidplayfp?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.16.0-1","2.16.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsidplayfp6","binary_version":"2.16.1-1"},{"binary_name":"libstilview0","binary_version":"2.16.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111148.json"}},{"package":{"name":"libsidplayfp","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libsidplayfp?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.12.0-1","2.15.1-1","2.15.2-1","2.16.0-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsidplayfp6","binary_version":"2.16.0-1"},{"binary_name":"libstilview0","binary_version":"2.16.0-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111148.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:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
