Red Hat, Inc. Security Advisory
Synopsis: New ed packages available
Advisory ID: RHSA-2000:123-01
Issue date: 2000-12-06
Updated on: 2000-12-06
Product: Red Hat Linux
Keywords: ed mktemp mkstemp /tmp
Cross references: N/A
---------------------------------------------------------------------
1. Topic:
The ed editor 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:
Red Hat Linux 5.2 - i386, alpha, sparc
Red Hat Linux 6.0 - i386, alpha, sparc
Red Hat Linux 6.1 - i386, alpha, sparc
Red Hat Linux 6.2 - i386, alpha, sparc
Red Hat Linux 7.0 - i386, alpha
3. Problem description:
The ed executable creates files in /tmp with predictable
names. By using various symlink attacks, it is possible to
have ed write to files it should not, change the permissions
of various files, etc.
4. Solution:
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
21470 - ed uses mktemp + fopen for scratch files
