CVE-2022-44638

Name of the Vulnerable Software and Affected Versions Pixman versions prior to 0.42.2

Description The issue is related to an out-of-bounds write, also known as a heap-based buffer overflow, in the rasterize edges 8 function of the Pixman library. This occurs due to an integer overflow in pixman sample floor y. The exploitation of this issue could allow a remote attacker to execute arbitrary code. The library is used for low-level graphics rendering in various open-source projects, including X.Org, Cairo, Firefox, and composite managers based on the Wayland protocol.

Recommendations For Pixman versions prior to 0.42.2, update to version 0.42.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of the rasterize edges 8 function until a patch is available. Avoid using parameters that could lead to integer overflow in pixman sample floor y until the issue is resolved.
