Synopsis: ghostscript uses mktemp instead of mkstemp, and uses an improper LD_RUN_PATH Advisory ID: RHSA-2000:114-03 Issue date: 2000-11-22 Updated on: 2000-11-22 Product: Red Hat Linux Keywords: ghostscript mktemp LD_RUN_PATH Cross references: N/A

  1. Topic:

ghostscript makes use of mktemp instead of mkstemp to create temp files; and also uses improper LD_RUN_PATH values, causing it to search for libraries in the current directory.

  1. Relevant releases/architectures:

Red Hat Linux 5.0 - i386, alpha, sparc Red Hat Linux 5.1 - i386, alpha, sparc 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

  1. Problem description:

ghostscript makes use of mktemp to create temp files, which is an insecure and predictable apporoach, it is now patched to use mkstemp, which avoid the race condition on the name.

It also uses improper LD_RUN_PATH values, causing ghostscript to search for libraries to load in current directorys.

  1. Solution:

For each RPM for your particular architecture, run:

rpm -Fvh [filename]

where filename is the name of the RPM.

  1. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

20924 - gs reads libraries from current directory
