CVE-2011-1749: Linux-Nfs Nfs-Utils

Low severity, CVSS 3.3. EPSS: 0.3% chance of exploitation in the next 30 days.

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.

Affected products

• Linux-Nfs Nfs-Utils: up to and including 1.2.3; version 1.2.0 only; version 1.2.1 only; version 1.2.2 only
