CVE-2011-2724
CVSS v2.0
6.8
Medium
| Vector | AV:N/AC:M/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Samba versions prior to 3.5.15
Samba version 3.5.6
Samba version 3.5.10 and earlier
cifs-utils version 4.8.1
Description
The issue affects the confidentiality, integrity, and availability of protected information. It can be exploited remotely. The check mtab function in client/mount.cifs.c in mount.cifs in smbfs in Samba does not properly verify that the device name and mountpoint strings are composed of valid characters, which allows local users to cause a denial of service (mtab corruption) via a crafted string.
Recommendations
For Samba versions prior to 3.5.15, update to version 3.5.15 or later.
For Samba version 3.5.6, update to a newer version.
For Samba version 3.5.10 and earlier, update to a version later than 3.5.10.
For cifs-utils version 4.8.1, update to a newer version.
As a temporary workaround, consider restricting access to the vulnerable components until a patch is available.
