Mandrake Linux Security Advisory : smb4k (MDKSA-2005:157)

A severe security issue has been discovered in Smb4K. By linking a simple text file FILE to /tmp/smb4k.tmp or /tmp/sudoers, an attacker could get access to the full contents of the /etc/super.tab or /etc/sudoers file, respectively, because Smb4K didn’t check for the existance of these files before writing any contents. When using super, the attack also resulted in /etc/super.tab being a symlink to FILE.

Affected are all versions of the 0.4, 0.5, and 0.6 series of Smb4K.

The updated packages have been patched to correct this problem.
