{"id":"DEBIAN-CVE-2026-13705","details":"Imager versions before 1.032 for Perl have a heap out-of-bounds read in the bundled Imager::File::SGI reader via a 16-bit RLE literal run in read_rgb_16_rle.  read_rgb_16_rle guards each literal run with if (count \u003e data_left), but count is a pixel count while every 16-bit sample consumes two bytes. The copy loop reads inp[0] * 256 + inp[1] and advances two bytes per pixel, so a run with data_left / 2 \u003c count \u003c= data_left passes the guard yet consumes 2 * count bytes and reads past the end of the buffer. The 8-bit path is unaffected because there one pixel is one byte.  Reading a crafted SGI image through Imager-\u003eread triggers the over-read before the parser rejects the malformed image, which can crash the process.","modified":"2026-09-01T16:06:27.975290047Z","published":"2026-07-06T13:16:32.447Z","upstream":["CVE-2026-13705"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-13705"}],"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"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13705.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"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13705.json"}},{"package":{"name":"libimager-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libimager-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.032+dfsg-1"}]}],"versions":["1.027+dfsg-1","1.028+dfsg-1","1.029+dfsg-1","1.030+dfsg-1","1.031+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-13705.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:H/I:N/A:H"}]}
