CVE-2026-13708 (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::File::JPEG versions before 1.003 for Perl leak heap memory when reading a JPEG with repeated APP13 markers in i_readjpeg_wiol.
i_readjpeg_wiol walks the marker list libjpeg returns and, for each APP13 marker, allocates a new buffer with *iptc_itext = mymalloc(...) and overwrites the previous pointer without freeing it. Only the final payload is later turned into a Perl scalar and freed, so a JPEG with N such markers leaks the first N-1 payloads on every read.
In a long-lived process, such as an upload or thumbnailing service, repeated reads accumulate these leaks and exhaust available memory, a denial of service.
The same handler ships bundled in the Imager distribution, where versions before 1.032 are affected and the fix ships in 1.032.
