{"id":"DEBIAN-CVE-2026-110678","details":"Cpanel::JSON::XS versions before 4.80 for Perl allow memory exhaustion by buffering incremental input past max_size in incr_parse.  The parser appends each chunk to its buffer. In scalar or list context, it compares max_size with how far it has progressed, not with the buffer length. A chunk that starts with a NUL byte stops the parser before it progresses, and a call in void context skips the check, so the buffer grows without limit.  A peer streaming data to an incr_parse consumer can exhaust process memory regardless of max_size.","modified":"2026-10-20T05:00:06.754242738Z","published":"2026-10-19T20:47:26.398521498Z","upstream":["CVE-2026-110678"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-110678"}],"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-2026-110678.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-2026-110678.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-2026-110678.json"}}],"schema_version":"1.9.0"}
