Summary

Multiple buffer overflows in the (1) recognize_eps_file function (src/psgen.c) and (2) tilde_subst function (src/util.c) in GNU enscript 1.6.1, and possibly earlier, might allow remote attackers to execute arbitrary code via an epsf escape sequence with a long filename.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Buffer Overflow via Environment Variables
    This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
  • Overflow Buffers
    Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
  • Client-side Injection-induced Buffer Overflow
    This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
  • Filter Failure through Buffer Overflow
    In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
  • MIME Conversion
    An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

An updated enscript packages that fixes several security issues is now
available for Red Hat Enterprise Linux 2.1, 3, and 4.

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.

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."
