CVE-2024-33653

Code execution via BMP parser over-read

Published Jul 9, 2024 · Updated Aug 2, 2024

Out-of-bounds read in Siemens Simcenter Femap before V2406 allows attackers to execute code after a user opens a crafted BMP file. The BMP parser reads past the end of an allocated structure when processing attacker-controlled file data; Siemens has not disclosed a narrower function or field. Exploitation requires user interaction and runs code with the current process's privileges, while malformed input can also crash the application.
