{"id":"DEBIAN-CVE-2026-110755","details":"Text::CSV_XS versions before 1.65 for Perl allow quadratic CPU use by copying the unparsed remainder per record of CR-only input in getline.  With eol unset, the default, getline reads with Perl's default line separator, so input with CR-only line endings arrives as one chunk. After each record the parser copies the whole unparsed remainder into a new buffer, which the next call parses and copies again, so the work grows with the square of the input size.  A reader with default options that is sent CSV with classic Mac line endings spends seconds of CPU time on a megabyte of input.","modified":"2026-10-17T08:00:06.612609291Z","published":"2026-10-17T07:47:41.971631942Z","upstream":["CVE-2026-110755"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-110755"}],"affected":[{"package":{"name":"libtext-csv-xs-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libtext-csv-xs-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.49-1","1.49-1+deb12u1","1.50-1","1.51-1","1.52-1","1.53-1","1.54-1","1.55-1","1.56-1","1.57-1","1.59-1","1.60-1","1.61-1","1.62-1","1.64-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110755.json"}},{"package":{"name":"libtext-csv-xs-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libtext-csv-xs-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.60-1","1.60-1+deb13u1","1.61-1","1.62-1","1.64-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110755.json"}},{"package":{"name":"libtext-csv-xs-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libtext-csv-xs-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.60-1","1.61-1","1.62-1","1.64-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-110755.json"}}],"schema_version":"1.9.0"}
