description
ImageSharp versions before 4.1.1 can write outside a tile buffer while decoding tiled TIFF images using fax compression. An attacker who can supply such an image to an application may cause process termination and memory corruption; the application must decode attacker-controlled tiled, fax-compressed TIFF content.
mitigation
Upgrade ImageSharp to version 4.1.1 or later. Until upgraded, reject untrusted tiled TIFF files that use fax compression before decoding.
fixed in 4.1.1
outcome
Contextual: an exploit technique exists, but no deterministic check could cover this one.
source signals
