{"id":"UBUNTU-CVE-2026-102505","details":"Imager versions before 1.037 for Perl overflow a heap buffer fetching float samples from a paletted image in i_gsampf_fp. For a paletted image, getsamples() with type \"float\" allocates a buffer of one sample per pixel and fetches every requested channel of each pixel into it. Requesting more than one channel writes past its end. An attacker-supplied image controls the overflowing bytes through its palette.","modified":"2026-10-02T22:30:09.422145279Z","published":"2026-10-02T00:00:00Z","upstream":["CVE-2026-102505"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-102505"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-102505"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/43998313/"},{"type":"REPORT","url":"https://github.com/tonycoz/imager/security/advisories/GHSA-4rx6-cgv3-fmxp"},{"type":"REPORT","url":"https://github.com/tonycoz/imager/commit/aae49c6be065aa467e834105c816359394a634db.patch"},{"type":"REPORT","url":"https://metacpan.org/release/TONYC/Imager-1.037/changes"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2026/10/01/10"}],"affected":[{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.003+dfsg-1","1.004+dfsg-1","1.004+dfsg-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.004+dfsg-1build1","binary_name":"libimager-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102505.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.005+dfsg-2build1","1.006+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libimager-perl","binary_version":"1.006+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102505.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.011+dfsg-1","1.011+dfsg-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.011+dfsg-1build1","binary_name":"libimager-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102505.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.012+dfsg-1build1","1.012+dfsg-2","1.012+dfsg-2build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libimager-perl","binary_version":"1.012+dfsg-2build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102505.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.019+dfsg-2","1.020+dfsg-1","1.022+dfsg-1","1.023+dfsg-1","1.023+dfsg-1build1","1.023+dfsg-1build2"],"ecosystem_specific":{"binaries":[{"binary_name":"libimager-perl","binary_version":"1.023+dfsg-1build2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102505.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.027+dfsg-1","1.029+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libimager-perl","binary_version":"1.029+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-102505.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"},{"type":"Ubuntu","score":"medium"}]}
