Yellow Dog Linux Security Announcement
--------------------------------------
Package: enscript
Issue Date: January 27, 2002
Priority: medium
Advisory ID: YDU-20020127-5
1. Topic:
Updated enscript packages that fix insecure handling of
temporary files are available.
2. Problem:
GNU enscript is a program for converting ASCII files to PostScript(TM).
When it creates temporary files, it does so with predictable filenames in
a manner that would follow symbolic links. This could allow a local user
to overwrite files written by the user running enscript, or read the
contents of the temporary files.
(from Red Hat advisory)
3. Solution:
a) Updating via yup...
We suggest that you use the Yellow Dog Update Program (yup)
to keep your system up-to-date. The following command(s) will
automatically retrieve and install the fixed version of
this update onto your system:
yup update enscript
b) Updating manually...
The update can also be retrieved manually from our ftp site
below along with the rpm command that should be used to install
the update. (Please use a mirror site)
ftp://ftp.yellowdoglinux.com/pub/yellowdog/updates/yellowdog-2.1/ppc/
rpm -Fvh enscript-1.6.1-16.2.ppc.rpm

If you wish to verify that each package has not been corrupted or tampered with,
examine the md5sum with the following command: rpm --checksig --nogpg filename
