{"id":"DEBIAN-CVE-2026-110759","details":"Text::CSV_XS versions before 1.65 for Perl return a 0xFF byte that is not in the input for an empty last field followed by a lone CR in parse.  When the input to parse ends in a separator and a lone CR, the parser treats the end of the input as the next character and stores the end-of-file marker in the field as the byte 0xFF. With binary set, parse(\"a,\\r\") returns the fields \"a\" and \"\\xFF\". On UTF-8 flagged input the last field is a UTF-8 flagged string holding that lone byte, which is malformed UTF-8. The same input with a non-empty last field is rejected as an error.  A CRLF file read line by line and chomped ends this way when its last column is empty, so the application receives a byte that is not in its input.","modified":"2026-10-17T08:00:06.621619122Z","published":"2026-10-17T07:47:42.402199854Z","upstream":["CVE-2026-110759"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-110759"}],"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-2026-110759.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-2026-110759.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-2026-110759.json"}}],"schema_version":"1.9.0"}
