exuberant-ctags creates temporary files insecurely

Vulnerability Note VU#401808

Original Release Date: 2001-09-17 | Last Revised: 2001-09-17

Overview

Some versions of exuberant-ctags, a source code navigation utility, create and use temporary files insecurely, leading to local file corruption and possible denial-of-service.

Description

Exuberent-ctags is a source code navigation utility. It creates temporary files with predictable names in /tmp. Prior to creation, the utility does not check for existence of the temporary files. These files are created world-readable.

Impact

By creating symbolic links named as the temporary files, an attacker can cause exuberant-ctags to overwrite files writable by the user of exuberant-ctags. By creating similarly named files and protecting them against the user of exuberant-ctags, an attacker can deny use of this utility to a user.

Solution

Apply vendor patches; see the Systems Affected section below.
