Overview

CVE-2011-2724 is a low-severity vulnerability affecting samba samba. It was published on September 6, 2011 and has a CVSS 2.0 base score of 1.2 (LOW).

This vulnerability has a CVSS 2.0 base score of 1.2, rated LOW. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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 (1) device name and (2) mountpoint strings are composed of valid characters, which allows local users to cause a denial of service (mtab corruption) via a crafted string. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-0547.

Remediation

Check the references section for vendor advisories and patches from samba. Update samba to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
