Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed

9.8 CriticalFix available

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 address space, which fails and kills the process.

An attacker could craft an image with EXIF data that terminates a worker process.

Updated perl-Imager package fixes security vulnerabilities

The updated package fixes security vulnerabilities: The Imager package before 1.025 for Perl has a heap-based buffer overflow leading to denial of service, or possibly unspecified other impact, when the trim() method is called on a crafted input image. (CVE-2024-53901) 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. (CVE-2026-13705) Imager::File::JPEG versions before 1.003 for Perl leak heap memory when reading a JPEG with repeated APP13 markers in i_readjpeg_wiol. (CVE-2026-13708) Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed. (CVE-2026-14454)
