A buffer overflow in Boost might allow remote attacker(s) to execute arbitrary code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| dev-libs/boost | * | < 1.74.0-r2 | >= 1.74.0-r2 |
Boost is a set of C++ libraries, including the Boost.Regex library to process regular expressions.
It was discovered that Boost incorrectly sanitized ‘next_size’ and ‘max_size’ parameter in ordered_malloc() function when allocating memory.
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.
There is no known workaround at this time.
All Boost users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/boost-1.74.0-r2"
Two vulnerabilities have been reported in Boost, each one possibly resulting in a Denial of Service.

Boost is a set of C++ libraries, including the Boost.Regex library to process regular expressions.
Tavis Ormandy and Will Drewry from the Google Security Team reported a failed assertion in file regex/v4/perl_matcher_non_recursive.hpp (CVE-2008-0171) and a NULL pointer dereference in function get_repeat_type() file basic_regex_creator.hpp (CVE-2008-0172) when processing regular expressions.
A remote attacker could provide specially crafted regular expressions to an application using Boost, resulting in a crash.
There is no known workaround at this time.
