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
==========
