http://security.gentoo.org/

Severity:	normal
Title:	Boost: Buffer overflow
Date:	05/26/2021
Bugs:	#620468
ID:	202105-04

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	Architecture(s)
dev-libs/boost	< 1.74.0-r2	>= 1.74.0-r2	All supported architectures

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"
