UNIX Domain Socket PID Value Control Vulnerability

CVE-2013-1958 · LOW Severity

AV:L/AC:M/AU:N/C:N/I:P/A:N

The scm_check_creds function in net/core/scm.c in the Linux kernel before 3.8.6 does not properly enforce capability requirements for controlling the PID value associated with a UNIX domain socket, which allows local users to bypass intended access restrictions by leveraging the time interval during which a user namespace has been created but a PID namespace has not been created.
