Red Hat, Inc. Security Advisory Synopsis: man package's 'makewhatis' uses insecure handling of files in /tmp Advisory ID: RHSA-2000:041-02 Issue date: 2000-07-03 Updated on: 2000-07-03 Product: Red Hat Linux Keywords: man /tmp makewhatis Cross references: N/A
The makewhatis portion of the man package used files in /tmp in an insecure fashion. It was possible for local users to exploit this vulnerability to modify files that they normally could not and gain elevated privilege.
2. Relevant releases/architectures:
3. Problem description:
The makewhatis script creates files in /tmp with predictable names. By using various symlink attacks, it is possible to have the makewhatis script write to files it should not, change the permissions of various files, etc.
It is recommended that users of Red Hat Linux upgrade to the fixed packages.
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
