CVE-2024-22043

Application crash via malformed XT file parsing

Published Feb 13, 2024 · Updated Aug 1, 2024

Null pointer dereference in Siemens Parasolid 35.0 and 35.1 allows context-dependent attackers to crash the host application via a crafted XT file. The XT parser dereferences a null pointer while reading malformed file content; Siemens has not identified the affected function or parsing operation. A user must open the untrusted file, and the resulting service interrupt is limited to the current application process.
