{"id":"DEBIAN-CVE-2023-44821","details":"Gifsicle through 1.94, if deployed in a way that allows untrusted input to affect Gif_Realloc calls, might allow a denial of service (memory consumption). NOTE: this has been disputed by multiple parties because the Gifsicle code is not commonly used for unattended operation in which new input arrives for a long-running process, does not ship with functionality to link it into another application as a library, and does not have realistic use cases in which an adversary controls the entire command line.","modified":"2026-09-15T09:02:32.077817048Z","published":"2023-10-09T20:15:10.583Z","upstream":["CVE-2023-44821"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-44821"}],"affected":[{"package":{"name":"gifsicle","ecosystem":"Debian:12","purl":"pkg:deb/debian/gifsicle?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.93-2","1.94-1","1.95-1","1.95-2","1.96-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-44821.json"}},{"package":{"name":"gifsicle","ecosystem":"Debian:13","purl":"pkg:deb/debian/gifsicle?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.96-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-44821.json"}},{"package":{"name":"gifsicle","ecosystem":"Debian:14","purl":"pkg:deb/debian/gifsicle?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.96-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-44821.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
