Gentoo Linux Security Advisory

Title: Boost: Buffer overflow (GLSA 202105-04)
Severity: normal
Exploitable: local, remote
Date: 2021-05-26
Bug(s): #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: dev-libs/boost
Vulnerable: < 1.74.0-r2
Unaffected: >= 1.74.0-r2
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/boost-1.74.0-r2"
