CVE-2023-31854Public exploit

Process abort via uncaught allocation exception

Published Mar 27, 2024 · Updated Aug 20, 2024

Resource exhaustion in Precomp 0.4.8 allows local users to abort the process by processing a specially crafted input file. A supplied file processed in recursive mode triggers an allocation failure, and the resulting std::bad_alloc exception escapes handling and terminates the process. The demonstrated impact is limited to that invocation, and the CVE is disputed as a usability problem rather than a security vulnerability.
