AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N

Name of the Vulnerable Software and Affected Versions Imager versions prior to 1.031

Description Imager for Perl allows a heap out of bounds (OOB) write—a memory corruption where data is written outside the boundaries of an allocated heap buffer—when processing crafted multi-frame GIF files. The i readgif multi low function in Imager::File::GIF allocates a single per-row buffer GifRow based on the global screen width SWidth and reuses it for every image in the file. While the page-match branch validates that Image.Width + Image.Left is not greater than SWidth before writing, the skip-image branch calls the DGifGetLine() function without performing this check.

Recommendations Update to a version later than 1.030.
