Name of the Vulnerable Software and Affected Versions Vanetza versions 26.02 and earlier

Description A denial-of-service issue exists in the ASN.1/OER parsing pipeline. When the system processes malformed network packets containing corrupted ASN.1/OER structures, such as invalid length fields or malformed certificate encoding, the ASN.1 wrapper asn1c wrapper.cpp raises a std::runtime error. Because this exception is not caught at the parsing boundary, it propagates to std::terminate(), causing the process to terminate.

Recommendations Update to the version containing commit 62dfe58a8342512b6e1947d75821402ada524f1a.
