Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-202003-13 (musl: x87 floating-point stack adjustment imbalance)

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.

Solution

All musl users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=sys-libs/musl-1.1.24'
