Weaknesses (CWE)

CWE-362Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')CWE-476NULL Pointer Dereference

Description

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.
