Detail

Synopsis

Multiple vulnerabilities were found in mount-cifs, the worst of which leading to privilege escalation.

Background

mount-cifs is the cifs filesystem mount helper split from Samba.

Description

Multiple vulnerabilities have been discovered in mount-cifs. Please review the CVE identifiers referenced below for details.

Impact

The vulnerabilities allow local users to cause a denial of service
(mtab corruption) via a crafted string. Also, local users could mount a CIFS share on an arbitrary mountpoint, and gain privileges via a symlink attack on the mountpoint directory file.

Workaround

There is no known workaround at this time.

Resolution

All mount-cifs users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-fs/mount-cifs-3.4.6"

Title: DSA-2004-1 samba -- several
Description: Two local vulnerabilities have been discovered in samba, a SMB/CIFS file, print, and login server for Unix. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-3297 Ronald Volgers discovered that a race condition in mount.cifs allows local users to mount remote filesystems over arbitrary mount points. CVE-2010-0547 Jeff Layton discovered that missing input sanitising in mount.cifs allows denial of service by corrupting /etc/mtab. For the stable distribution, these problems have been fixed in version 2:3.2.5-4lenny9. For the unstable distribution, these problems have been fixed in version 2:3.4.5~dfsg-2. We recommend that you upgrade your samba packages.
