Synopsis
========

A buffer overflow in Boost might allow remote attacker(s) to execute
arbitrary code.

Background
==========

Boost is a set of C++ libraries, including the Boost.Regex library to
process regular expressions.

Affected packages
=================

     -------------------------------------------------------------------
      Package              /     Vulnerable     /            Unaffected
     -------------------------------------------------------------------
   1  dev-libs/boost             < 1.74.0-r2              >= 1.74.0-r2

Description
===========

It was discovered that Boost incorrectly sanitized 'next_size' and
'max_size' parameter in ordered_malloc() function when allocating
memory.

Impact
======

A remote attacker could provide a specially crafted
application-specific file (requiring runtime memory allocation to be
processed correctly), that, when opened with an application using Boost
C++ source libraries, possibly resulting in execution of arbitrary code
with the privileges of the process or a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Boost users should upgrade to the latest version:

   # emerge --sync
   # emerge --ask --oneshot --verbose ">=dev-libs/boost-1.74.0-r2"

References
==========

[ 1 ] CVE-2012-2677
