Kerentanan Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'). Skor CVSS 3.1 5.7 (Medium) menurut github.com.

Deskripsi (NVD)

pam_usb provides hardware authentication for Linux using ordinary removable media. 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.
