Descriptions
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.
La función nfs_addmntent en support/nfs/nfs_mntent.c en la herramienta mount.nsf en nfs-utils anterior a 1.2.4 intenta añadir al archivo /etc/mtab sin primero comprobar si los limites del recurso interfieren, lo que permite a usuarios locales corromper este archivo a través de un proceso con un valor RLIMIT_FSIZE pequeño, un problema relacionado con CVE-2011-1089.
