Synopsis ========
A stack-based buffer overflow in musl might allow an attacker to have an application dependent impact.
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 ==========
