CVE-2011-1678

Status Candidate

Overview

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.

Mandriva Linux Security Advisory 2011-148

Mandriva Linux Security Advisory 2011-148 - Multiple vulnerabilities has been discovered and corrected in samba/cifs-utils. smbfs in Samba 3.5.8 and earlier attempts to use mount.cifs to append to the /etc/mtab file and 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. The check_mtab function in client/mount.cifs.c in mount.cifs in smbfs in Samba 3.5.10 and earlier does not properly verify that the mountpoint strings are composed of valid characters, which allows local users to cause a denial of service via a crafted string. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-0547. Additionally for Mandriva Linux 2010.2 the cifs-utils package has been upgraded to the 4.8.1 version that brings numerous additional fixes.

Red Hat Security Advisory 2011-1221-01

Red Hat Security Advisory 2011-1221-01 - Samba is a suite of programs used by machines to share files, printers, and other information. The cifs-utils package contains utilities for mounting and managing CIFS shares. A cross-site scripting flaw was found in the password change page of the Samba Web Administration Tool. If a remote attacker could trick a user, who was logged into the SWAT interface, into visiting a specially-crafted URL, it would lead to arbitrary web script execution in the context of the user's SWAT session. It was found that SWAT web pages did not protect against Cross-Site Request Forgery attacks. If a remote attacker could trick a user, who was logged into the SWAT interface, into visiting a specially-crafted URL, the attacker could perform Samba configuration changes with the privileges of the logged in user.
