Overview

Affected versions of this package are vulnerable to Use After Free in the smb2_is_status_io_timeout() function in CIFS. An attacker can cause a denial of service by exploiting a use-after-free flaw. This occurs when CIFS transfers response data to a system call, and local variables still point to the memory region. If the system call frees this memory faster than CIFS uses it, CIFS will access a freed memory region.
