CVE-2011-1089

glibc: Suid mount helpers fail to anticipate RLIMIT_FSIZE

Published Apr 10, 2011 CVSS 2.0 · 3.3 Low EPSS < 1% KEV · Not listed
Description
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.
