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 ========== [ 1 ] CVE-2012-2677 https://nvd.nist.gov/vuln/detail/CVE-2012-2677 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202105-04 Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
