Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200711-28
(Perl: Buffer overflow)

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 :

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

Workaround :

There is no known workaround at this time.
