Security Advisories for Imager in cpan

Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed. Imager mishandled large EXIF IFD entry count values, treating them as negative numbers. This could lead to an attempt to allocate a block nearly the size of the add... CPANSA-Imager-2026-14454

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_... CPANSA-Imager-File-JPEG-2026-13708

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 cou... CPANSA-Imager-2026-13705

Imager versions through 1.030 for Perl allow a heap out of bounds (OOB) write on crafted multi-frame GIF files. Imager::File::GIF's i_readgif_multi_low allocates a single per-row buffer GifRow sized for the GIF's global screen width 'SWidth' and reuse... CPANSA-Imager-2026-8669

When drawing on an image with an alpha channel where the source minimum is greater than zero, Imager would read from beyond the end of a malloc() allocated buffer. In rare circumstances this could lead to some of the source image not being written to ... CPANSA-Imager-2014-01

Buffer overflow in Imager 0.42 through 0.63 allows attackers to cause a denial of service (crash) via an image based fill in which the number of input channels is different from the number of output channels. CPANSA-Imager-2008-1928

Heap-based buffer overflow in the BMP reader (bmp.c) in Imager perl module (libimager-perl) 0.45 through 0.56 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted 8-bit/pixel compresse... CPANSA-Imager-2007-2459

Imager (libimager-perl) before 0.50 allows user-assisted attackers to cause a denial of service (segmentation fault) by writing a 2- or 4-channel JPEG image (or a 2-channel TGA image) to a scalar, which triggers a NULL pointer dereference. CPANSA-Imager-2006-0053
