CVE-2014-1874

Published: 7 February 2014

The security_context_to_sid_core function in security/selinux/ss/services.c in the Linux kernel before 3.13.4 allows local users to cause a denial of service (system crash) by leveraging the CAP_MAC_ADMIN capability to set a zero-length security context.

From the Ubuntu security team

Matthew Thode reported a denial of service vulnerability in the Linux kernel when SELinux support is enabled. A local user with the CAP_MAC_ADMIN capability (and the SELinux mac_admin permission if running in enforcing mode) could exploit this flaw to cause a denial of service (kernel crash).
