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 type="normal">
|
|
<p>
|
|
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.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All enscript users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/enscript-1.6.4-r4"</code>
