What is CVE-2026-8669?

The Imager library for Perl is susceptible to a heap out of bounds (OOB) write vulnerability when processing crafted multi-frame GIF files. The issue arises from the i_readgif_multi_low method in Imager::File::GIF, which improperly allocates a single per-row buffer. This could allow an attacker to exploit the vulnerability by manipulating the dimensions of the GIF images, subsequently leading to instability and potential software crashes.
