{"id":"UBUNTU-CVE-2026-40494","details":"SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to commit 45d48d1f2e8e0d73e80bc1fd5310cb57f4547302, the TGA codec's RLE decoder in `tga.c` has an asymmetric bounds check vulnerability. The run-packet path (line 297) correctly clamps the repeat count to the remaining buffer space, but the raw-packet path (line 305-311) has no equivalent bounds check. This allows writing up to 496 bytes of attacker-controlled data past the end of a heap buffer. Commit 45d48d1f2e8e0d73e80bc1fd5310cb57f4547302 patches the issue.","modified":"2026-05-20T16:25:39.848630471Z","published":"2026-04-18T03:16:00Z","upstream":["CVE-2026-40494"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-40494"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-40494"},{"type":"REPORT","url":"https://github.com/HappySeaFox/sail/security/advisories/GHSA-cp2j-rwh4-r46f"}],"affected":[{"package":{"name":"sail","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/sail?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.0+repack-1","0.9.0+repack-2","0.9.0+repack-2.1","0.9.0+repack-2.1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsail-c++0t64","binary_version":"0.9.0+repack-2.1build1"},{"binary_name":"libsail-common0t64","binary_version":"0.9.0+repack-2.1build1"},{"binary_version":"0.9.0+repack-2.1build1","binary_name":"libsail-manip0t64"},{"binary_name":"libsail0t64","binary_version":"0.9.0+repack-2.1build1"},{"binary_version":"0.9.0+repack-2.1build1","binary_name":"sail-codecs"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-40494.json"}},{"package":{"name":"sail","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/sail?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.7-1build1","0.9.8-1","0.9.9-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsail-c++0t64","binary_version":"0.9.9-1"},{"binary_name":"libsail-common0t64","binary_version":"0.9.9-1"},{"binary_name":"libsail-manip0t64","binary_version":"0.9.9-1"},{"binary_name":"libsail0t64","binary_version":"0.9.9-1"},{"binary_name":"sail-codecs","binary_version":"0.9.9-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-40494.json"}},{"package":{"name":"sail","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/sail?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.9-1","0.9.10-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libsail-c++0t64","binary_version":"0.9.10-1"},{"binary_version":"0.9.10-1","binary_name":"libsail-common0t64"},{"binary_version":"0.9.10-1","binary_name":"libsail-manip0t64"},{"binary_version":"0.9.10-1","binary_name":"libsail0t64"},{"binary_name":"sail-codecs","binary_version":"0.9.10-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-40494.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
