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
The Perl Imager module (versions 0.45_02 before 1.034 ) is vulnerable to a heap over-read in the copy_string_tags() function. The root cause is that a zero-count ASCII EXIF entry sets entry->size to 0, resulting in a length of -1; this causes i_tags_add() to invoke strlen(), which scans past t...
CVE-2026-14454
The Imager module for Perl (versions before 1.033 ) contains a vulnerability where it mishandles large EXIF IFD entry count values by treating them as signed numbers. This logic error allows an attacker to craft an image with malicious EXIF data, causing the software to attempt to allocate a memo...
