CyberRota Analysis
AI-GeneratedVersions of Imager::File::JPEG prior to 1.032 for Perl are vulnerable to a heap memory leak when processing JPEG files with multiple APP13 markers, leading to potential denial of service due to memory exhaustion. This vulnerability can significantly impact long-lived processes, such as upload or thumbnailing services, that repeatedly read affected JPEG files. Organizations utilizing these services should prioritize patching to version 1.032 or later to mitigate the risk.

Original NVD Description
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.
