GLSA-200511-15 : Smb4k: Local unauthorized file access

low Nessus Plugin ID 20236

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200511-15 (Smb4k: Local unauthorized file access)

 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.
 Impact :

 An attacker could acquire local privilege escalation by adding username(s) to the list of sudoers.
 Workaround :

 There is no known workaround at this time.

Solution

All smb4k users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/smb4k-0.6.4'
