"The remote Oracle Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the
ELSA-2011-1534 advisory.
- 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. (CVE-2011-1749)
- The host_reliable_addrinfo function in support/export/hostname.c in nfs-utils before 1.2.4 does not
properly use DNS to verify access to NFS exports, which allows remote attackers to mount filesystems by
establishing crafted DNS A and PTR records. (CVE-2011-2500)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
