{"id":"UBUNTU-CVE-2026-13708","details":"Imager::File::JPEG versions before 1.003 for Perl leak heap memory when reading a JPEG with repeated APP13 markers in i_readjpeg_wiol. i_readjpeg_wiol walks the marker list libjpeg returns and, for each APP13 marker, allocates a new buffer with *iptc_itext = mymalloc(...) and overwrites the previous pointer without freeing it. Only the final payload is later turned into a Perl scalar and freed, so a JPEG with N such markers leaks the first N-1 payloads on every read. In a long-lived process, such as an upload or thumbnailing service, repeated reads accumulate these leaks and exhaust available memory, a denial of service. The same handler ships bundled in the Imager distribution, where versions before 1.032 are affected and the fix ships in 1.032.","modified":"2026-07-09T17:15:13.783906218Z","published":"2026-07-06T13:16:00Z","upstream":["CVE-2026-13708"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-13708"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-13708"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/41572486/"}],"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-2026-13708.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-2026-13708.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-2026-13708.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-2026-13708.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_version":"1.023+dfsg-1build2","binary_name":"libimager-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-13708.json"}},{"package":{"name":"libimager-perl","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/libimager-perl?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.027+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.027+dfsg-1","binary_name":"libimager-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-13708.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-2026-13708.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:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
