Amazon Linux AMI : libcap-ng (ALAS-2015-543)
Medium Nessus Plugin ID 84244
SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionA 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.
SolutionRun 'yum update libcap-ng' to update your system.
