Descriptions

smbfs in Samba 3.5.8 and earlier attempts to use (1) mount.cifs to append to the /etc/mtab file and (2) umount.cifs to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089.

smbfs en Samba v3.5.8 y anteriores, un intento de utilizar (1) mount.cifs para añadir al fichero /etc/mtab y (2) umount.cifs para añadir al fichero /etc/mtab.tmp sin primero verificar si los límites del recursos pudieran interferir, permitiría a usuarios locales provocar la corrupción del fichero /etc/mtab a través de un proceso con un valor RLIMIT_FSIZE pequeño, un asunto relacionado con CVE-2011-1089.
