Debian Testing Security Advisory DTSA-25-1              December 5th, 2005

Package        : smb4k
Vulnerability  : access validation error
Problem-Scope  : local
Debian-specific: No
CVE ID         : CVE-2005-2851 

CVE-2005-2851

	 A vulnerability leading to unauthorized file access has been found. A
	 pre-existing symlink from /tmp/sudoers and /tmp/super.tab to a textfile
	 will cause Smb4k to write the contents of these files to the target of the
	 symlink, as Smb4k does not check for the existence of these files before
	 writing to them. 

For the testing distribution (etch) this is fixed in version
0.6.4-0.0etch1

For the unstable distribution (sid) this is fixed in version
0.6.4-1

This upgrade is recommended if you use smb4k.

The Debian testing security team does not track security issues for the
stable (sarge) and oldstable (woody) distributions. If stable is vulnerable,
the Debian security team will make an announcement once a fix is ready.
