3. Description:
GNU enscript converts ASCII files to PostScript(R) language files and
spools the generated output to a specified printer or saves it to a file.
Enscript can be extended to handle different output media and includes
options for customizing printouts.
Several buffer overflow flaws were found in GNU enscript. An attacker could
craft an ASCII file in such a way that it could execute arbitrary commands
if the file was opened with enscript with the "special escapes" option (-e
or --escapes) enabled. (CVE-2008-3863, CVE-2008-4306, CVE-2008-5078)
All users of enscript should upgrade to these updated packages, which
contain backported patches to correct these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
