{"id":"DEBIAN-CVE-2026-110758","details":"Text::CSV_XS versions before 1.65 for Perl read before the start of an all-blank field under allow_whitespace in strip_trail_whitespace.  Under allow_whitespace, strip_trail_whitespace removes trailing spaces and tabs from each unquoted field without stopping at the start of the field. For a field of only blanks it reads the byte before the field's heap buffer. If that byte is also a space or tab, it may be zeroed and the walk continue backwards, depending on what the allocator placed there.  Leading blanks are normally skipped before a field is stored, but an all-blank field still arrives after a leading escape_char that differs from quote_char, or as a quoted field in getline when its line ends in two CRs.","modified":"2026-10-17T08:00:06.580895036Z","published":"2026-10-17T07:47:33.615440961Z","upstream":["CVE-2026-110758"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-110758"}],"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-2026-110758.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-2026-110758.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-2026-110758.json"}}],"schema_version":"1.9.0"}
