How to fix?

Upgrade Debian:11 pixman to version 0.40.0-1.1~deb11u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream pixman package and not the pixman package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

In libpixman in Pixman before 0.42.2, there is an out-of-bounds write (aka heap-based buffer overflow) in rasterize_edges_8 due to an integer overflow in pixman_sample_floor_y.
