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. 5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info): N/A 6.
