A buffer overflow in Boost might allow remote attacker(s) to execute arbitrary code.
|Package||dev-libs/boost on all architectures|
|Affected versions||< 1.74.0-r2|
|Unaffected versions||>= 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"
