Description
Description
The Affinity by Canva application before 3.3.1 (October 2026 release) did not perform adequate bounds checking when parsing raster image data in Affinity document files, leading to an out-of-bounds read and the dereference of an untrusted pointer. A threat actor could craft an Affinity document that, when opened by a user in Affinity, could result in memory corruption or an application crash.
