CVE-2026-19082

Imager versions from 0.4502 before 1.034 for Perl may expose adjacent heap bytes via strlen over-read from zero-count ASCII EXIF entries in copystringtags. copystringtags computes an ASCII EXIF tag's length as entry-size - 1 to strip the trailing NUL. A zero-count ASCII entry sets entry-size to 0...

CVE-2026-19082

Affected product: Imager (Perl) versions from 0.45_02 up to (but not including) 1.034. Root cause: copy_string_tags computes tag length as entry->size - 1; when entry->size is 0 (zero-count ASCII EXIF entry), i_tags_add() uses -1, causing strlen() to read past the entry and copy adjacent he...
