CVE-2011-1749  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade RHEL:6 nfs-utils to version 1:1.2.3-15.el6 or higher.
This issue was patched in RHSA-2011:1534.

NVD Description

Note: Versions mentioned in the description apply only to the upstream nfs-utils package and not the nfs-utils package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

The nfs_addmntent function in support/nfs/nfs_mntent.c in the mount.nsf tool in nfs-utils before 1.2.4 attempts to append to the /etc/mtab file without first checking whether resource limits would interfere, which allows local users to corrupt this file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089.
