The addmntent function in the GNU C Library (aka glibc or libc6) 2.13 and
earlier does not report an error status for failed attempts to write to the
/etc/mtab file, which makes it easier for local users to trigger corruption
of this file, as demonstrated by writes from a process with a small
RLIMIT_FSIZE value, a different vulnerability than CVE-2010-0296.
