Prior to 0.9.1, src/log.c contains a process-wide static pointer that is written on every PAM invocation with the address of a stack-local variable. This violates the PAM re-entrancy requirement and creates a data race when the PAM stack is invoked concurrently from multiple threads. This vulnerability is fixed in 0.9.1."}], "lastModified": "2026-05-28T13:57:25.390", "sourceIdentifier": "security-advisories@github.com"}
