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
