|
|
Tavis Ormandy and Will Drewry (Google Security Team) discovered a
|
|
heap-based buffer overflow in the Regular Expression engine (regcomp.c)
|
|
that occurs when switching from byte to Unicode (UTF-8) characters in a
|
|
regular expression.

<impact type="normal">
|
|
<p>
|
|
A remote attacker could either entice a user to compile a specially
|
|
crafted regular expression or actively compile it in case the script
|
|
accepts remote input of regular expressions, possibly leading to the
|
|
execution of arbitrary code with the privileges of the user running
|
|
Perl.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Perl users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-lang/perl-5.8.8-r4"</code>
