CVE-2026-19082 (opens in a new tab)How to fix?
There is no fixed version for Echo:latest libimager-perl.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libimager-perl package and not the libimager-perl package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
Imager versions from 0.45_02 before 1.034 for Perl may expose adjacent heap bytes via strlen() over-read from zero-count ASCII EXIF entries in copy_string_tags.
copy_string_tags() 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, and the derived length reaches i_tags_add() as -1, which is interpreted as a request to call strlen(), scanning past the entry to the next NUL and copying those bytes into the tag. JPEG reaches this path via im_decode_exif(), as does the separate Imager::File::WEBP distribution, which is fixed by upgrading Imager.
Any caller of Imager->read() on an attacker-supplied image with such an entry may receive an exif_* tag holding adjacent heap bytes instead of an empty string.
