{"id":"DEBIAN-CVE-2026-102504","details":"Imager versions before 1.037 for Perl exit the process reading a raw image with an out-of-range raw_datachannels value in i_readraw_wiol.  Nothing range-checks raw_datachannels. The line buffer is sized as the image width times the channel count with no overflow check, so a negative or very large count requests an excessive allocation. When it fails, Imager's allocator calls exit(3).  Passing an untrusted raw_datachannels value to Imager-\u003eread() triggers an uncatchable exit.","modified":"2026-10-02T05:01:06.563517858Z","published":"2026-10-01T14:17:20.080Z","upstream":["CVE-2026-102504"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-102504"}],"affected":[{"package":{"name":"libimager-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libimager-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.019+dfsg-1","1.019+dfsg-2","1.020+dfsg-1","1.022+dfsg-1","1.023+dfsg-1","1.024+dfsg-1","1.024+dfsg-2","1.025+dfsg-1","1.027+dfsg-1","1.028+dfsg-1","1.029+dfsg-1","1.030+dfsg-1","1.031+dfsg-1","1.032+dfsg-1","1.033+dfsg-1","1.034+dfsg-1","1.034+dfsg-2","1.035+dfsg-1","1.036+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-102504.json"}},{"package":{"name":"libimager-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libimager-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.027+dfsg-1","1.028+dfsg-1","1.029+dfsg-1","1.030+dfsg-1","1.031+dfsg-1","1.032+dfsg-1","1.033+dfsg-1","1.034+dfsg-1","1.034+dfsg-2","1.035+dfsg-1","1.036+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-102504.json"}},{"package":{"name":"libimager-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libimager-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.027+dfsg-1","1.028+dfsg-1","1.029+dfsg-1","1.030+dfsg-1","1.031+dfsg-1","1.032+dfsg-1","1.033+dfsg-1","1.034+dfsg-1","1.034+dfsg-2","1.035+dfsg-1","1.036+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-102504.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
