Gentoo Linux Security Advisory

Title: Smb4k: Local unauthorized file access (GLSA 200511-15)
Severity: high
Exploitable: local
Date: November 18, 2005
Bug(s): #111089
ID: 200511-15

Synopsis

A vulnerability has been identified that allows unauthorized access to the contents of /etc/sudoers and /etc/super.tab files.

Background

Smb4K is a SMB/CIFS share browser for KDE.

Affected Packages

Package: net-misc/smb4k
Vulnerable: < 0.6.4
Unaffected: >= 0.6.4
Architectures: All supported architectures


Description

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.

Resolution

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