Vulnerability Assessment Details

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

Vulnerability Assessment Summary
Smb4k: Local unauthorized file access

Detailed Explanation for this Vulnerability Assessment
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

A possible hacker could acquire local privilege escalation by adding
username(s) to the list of sudoers.

Workaround

There is no known workaround at this time.
