Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Two buffer overflows in enscript might lead to the execution of |
| 19 |
arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
enscript is a powerful ASCII to PostScript file converter. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|

------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |

| 32 |
1 app-text/enscript < 1.6.4-r4 >= 1.6.4-r4 |

Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Two stack-based buffer overflows in the read_special_escape() function |
| 38 |
in src/psgen.c have been reported. Ulf Harnhammar of Secunia Research |
| 39 |
discovered a vulnerability related to the "setfilename" command |
| 40 |
(CVE-2008-3863), and Kees Cook of Ubuntu discovered a vulnerability |
| 41 |
related to the "font" escape sequence (CVE-2008-4306). |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
An attacker could entice a user or automated system to process |
| 47 |
specially crafted input with the special escapes processing enabled |
| 48 |
using the "-e" option, possibly resulting in the execution of arbitrary |
| 49 |
code. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
There is no known workaround at this time. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All enscript users should upgrade to the latest version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose ">=app-text/enscript-1.6.4-r4" |
| 63 |
|
