{"id":"DEBIAN-CVE-2020-29385","details":"GNOME gdk-pixbuf (aka GdkPixbuf) before 2.42.2 allows a denial of service (infinite loop) in lzw.c in the function write_indexes. if c-\u003eself_code equals 10, self-\u003ecode_table[10].extends will assign the value 11 to c. The next execution in the loop will assign self-\u003ecode_table[11].extends to c, which will give the value of 10. This will make the loop run infinitely. This bug can, for example, be triggered by calling this function with a GIF image with LZW compression that is crafted in a special way.","modified":"2026-09-01T16:05:01.059221184Z","published":"2020-12-26T02:15:12.807Z","upstream":["CVE-2020-29385"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2020-29385"}],"affected":[{"package":{"name":"gdk-pixbuf","ecosystem":"Debian:12","purl":"pkg:deb/debian/gdk-pixbuf?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.42.2+dfsg-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2020-29385.json"}},{"package":{"name":"gdk-pixbuf","ecosystem":"Debian:13","purl":"pkg:deb/debian/gdk-pixbuf?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.42.2+dfsg-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2020-29385.json"}},{"package":{"name":"gdk-pixbuf","ecosystem":"Debian:14","purl":"pkg:deb/debian/gdk-pixbuf?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.42.2+dfsg-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2020-29385.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:N/I:N/A:H"}]}
