{"id":"DEBIAN-CVE-2026-110685","details":"Cpanel::JSON::XS versions before 4.80 for Perl leak the decoded arguments of a tagged value when its THAW method dies in decode_tag.  With allow_tags, a tagged value's class name and argument array are decoded and passed to the class's THAW method. Both are released only after THAW returns, so a THAW that dies leaves the whole decoded argument structure allocated.  Each rejected document leaks data of a size the sender chooses, so a process that catches the error and keeps running exhausts its memory.","modified":"2026-10-20T05:00:06.734727120Z","published":"2026-10-19T20:47:27.003726313Z","upstream":["CVE-2026-110685"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-110685"}],"affected":[{"package":{"name":"libcpanel-json-xs-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libcpanel-json-xs-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.35-1","4.35-1+deb12u1","4.36-1","4.37-1","4.38-1","4.39-1","4.39-2","4.39-2~deb13u1","4.40-1","4.41-1","4.42-1","4.51-1","4.80-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110685.json"}},{"package":{"name":"libcpanel-json-xs-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libcpanel-json-xs-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.39-1","4.39-2","4.39-2~deb13u1","4.40-1","4.41-1","4.42-1","4.51-1","4.80-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110685.json"}},{"package":{"name":"libcpanel-json-xs-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libcpanel-json-xs-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.39-1","4.39-2","4.39-2~deb13u1","4.40-1","4.41-1","4.42-1","4.51-1","4.80-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110685.json"}}],"schema_version":"1.9.0"}
