Red Hat, Inc. Security Advisory
Synopsis: xpdf bugfix release
Advisory ID: RHSA-2000:060-03
Issue date: 2000-09-13
Updated on: 2000-09-13
Product: Red Hat Linux
Keywords: security problem in temporary file and malicious URL.
Cross references: N/A
1. Topic:
Security problem in temporary file and malicious URL.
2. Relevant releases/architectures:
Red Hat Linux 5.2 – i386, alpha, sparc
Red Hat Linux 6.2 – i386, alpha, sparc
3. Problem description:
There is a security problem when using tmpnam() and fopen() in
versions prior to 0.91. The problem is seen when a root user
overwrites files where a symlink is created between the calls to
tmpname() and fopen().
There is also a problem with URL-type links in PDF documents
that contain quote characters which could also be used to execute
arbitrary commands.
The xpdf-0.91 fixes both these security problems.
4. Solution:
For each RPM for your particular architecture, run:
rpm -Fvh [filename]
where filename is the name of the RPM.
