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 Debian.
See How to fix? for Debian:12 relevant fixed versions and status.
Imager versions before 1.032 for Perl have a heap out-of-bounds read in the bundled Imager::File::SGI reader via a 16-bit RLE literal run in read_rgb_16_rle.
read_rgb_16_rle guards each literal run with if (count > data_left), but count is a pixel count while every 16-bit sample consumes two bytes. The copy loop reads inp[0] * 256 + inp[1] and advances two bytes per pixel, so a run with data_left / 2 < count <= data_left passes the guard yet consumes 2 * count bytes and reads past the end of the buffer. The 8-bit path is unaffected because there one pixel is one byte.
Reading a crafted SGI image through Imager->read triggers the over-read before the parser rejects the malformed image, which can crash the process.
