Red Hat Security Advisory 2015-0864-01

Posted Apr 21, 2015

Red Hat Security Advisory 2015-0864-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support.
