CVE-2024-26276

Process denial of service via X_T stack exhaustion

Published Apr 9, 2024 · Updated Aug 13, 2024

Stack exhaustion in X_T parsing in affected Siemens JT2Go, Parasolid, and Teamcenter Visualization releases allows attackers to interrupt the current process. Siemens has not disclosed the parser routine or recursive operation that exhausts the stack while handling the crafted file. Exploitation requires a user to open an untrusted X_T file, and the reported consequence is denial of service in the affected process.
