Gentoo Linux Security Advisory

Title: Smb4K: Multiple vulnerabilities (GLSA 200703-09)
Severity: high
Exploitable: local
Date: March 09, 2007
Bug(s): #156152
ID: 200703-09


Multiple vulnerabilities have been identified in Smb4K.


Smb4K is a SMB/CIFS (Windows) share browser for KDE.

Affected Packages

Package: net-misc/smb4k
Vulnerable: < 0.6.10a
Unaffected: >= 0.6.10a
Architectures: All supported architectures


Kees Cook of the Ubuntu Security Team has identified multiple vulnerabilities in Smb4K.
  • The writeFile() function of smb4k/core/smb4kfileio.cpp makes insecure usage of temporary files.
  • The writeFile() function also stores the contents of the sudoers file with incorrect permissions, allowing for the file's contents to be world-readable.
  • The createLockFile() and removeLockFile() functions improperly handle lock files, possibly allowing for a race condition in file handling.
  • The smb4k_kill utility distributed with Smb4K allows any user in the sudoers group to kill any process on the system.
  • Lastly, there is the potential for multiple stack overflows when any Smb4K utility is used with the sudo command.


A local attacker could gain unauthorized access to arbitrary files via numerous attack vectors. In some cases to obtain this unauthorized access, an attacker would have to be a member of the sudoers list.


There is no known workaround at this time.


All Smb4K users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/smb4k-0.6.10a"
