The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200710-18 (util-linux: Local privilege escalation)

Ludwig Nussel discovered that the check_special_mountprog() and check_special_umountprog() functions call setuid() and setgid() in the wrong order and do not check the return values, which can lead to privileges being dropped improperly.
Impact :

A local attacker may be able to exploit this vulnerability by using mount helpers such as the mount.nfs program to gain root privileges and run arbitrary commands.
Workaround :

There is no known workaround at this time.


All util-linux users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-apps/util-linux-2.12r-r8'
