Background ========== musl is an implementation of the C standard library built on top of the Linux system call API, including interfaces defined in the base language standard, POSIX, and widely agreed-upon extensions. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-libs/musl < 1.1.24 >= 1.1.24 Description =========== A flaw in musl libc's arch-specific math assembly code for i386 was found which can lead to x87 stack overflow in the execution of subsequent math code. Impact ====== Impact depends on how the application built against musl libc handles the ABI-violating x87 state. Workaround ========== There is no known workaround at this time. Resolution ========== All musl users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-libs/musl-1.1.24" References ========== [ 1 ] CVE-2019-14697 https://nvd.nist.gov/vuln/detail/CVE-2019-14697 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/202003-13 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.
