From Red Hat Security Advisory 2008:1016 :

An updated enscript packages that fixes several security issues is now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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.

Two 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)

All users of enscript should upgrade to these updated packages, which contain backported patches to correct these issues.

There were found various buffer overflows in enscript. This update fixes CVE-2008-3863 and CVE-2008-4306

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Ulf Harnhammar of Secunia Research reports :

Stack-based buffer overflow in the read_special_escape function in src/psgen.c in GNU Enscript 1.6.1 and 1.6.4 beta, when the -e (aka special escapes processing) option is enabled, allows user-assisted remote attackers to execute arbitrary code via a crafted ASCII file, related to the setfilename command.

Several vulnerabilities have been discovered in Enscript, a converter from ASCII text to Postscript, HTML or RTF. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2008-3863     Ulf Harnhammer discovered that a buffer overflow may     lead to the execution of arbitrary code.

  - CVE-2008-4306     Kees Cook and Tomas Hoger discovered that several buffer     overflows may lead to the execution of arbitrary code.

The remote host is affected by the vulnerability described in GLSA-200812-02 (enscript: User-assisted execution of arbitrary code)

    Two stack-based buffer overflows in the read_special_escape() function     in src/psgen.c have been reported. Ulf Harnhammar of Secunia Research     discovered a vulnerability related to the 'setfilename' command     (CVE-2008-3863), and Kees Cook of Ubuntu discovered a vulnerability     related to the 'font' escape sequence (CVE-2008-4306).
  Impact :

    An attacker could entice a user or automated system to process     specially crafted input with the special escapes processing enabled     using the '-e' option, possibly resulting in the execution of arbitrary     code.
  Workaround :

    There is no known workaround at this time.

Ulf Harnhammar discovered multiple stack overflows in enscript's handling of special escape arguments. If a user or automated system were tricked into processing a malicious file with the '-e' option enabled, a remote attacker could execute arbitrary code or cause enscript to crash, possibly leading to a denial of service.
