Summary

AMD Compressonator SDK contains an out-of-bounds write flaw (CWE-787) when it processes DirectDraw Surface (DDS) files. A local attacker who supplies a specially crafted DDS file to a user or an automated pipeline can corrupt heap memory or cause a denial of service. Exploitation requires that a user or pipeline processes the file.

Description from the CNA

An out-of-bounds write (OOW) condition in the AMD Compressonator SDK could allow an attacker with local access to supply a specially crafted DirectDraw Surface (DDS) file to a user or an automated pipeline, potentially resulting in heap corruption or denial of service (DoS).
