<title>musl: x87 floating-point stack adjustment imbalance</title>
<synopsis>An x87 stack handling error in musl might allow an attacker to have
an application dependent impact.

<affected>
<package name="sys-libs/musl" auto="yes" arch="*">
<unaffected range="ge">1.1.24</unaffected>
<vulnerable range="lt">1.1.24</vulnerable>
</package>

<background>
<p>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.
</p>
</background>
<description>
<p>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.
</p>
</description>
<impact type="normal">
<p>Impact depends on how the application built against musl libc handles
the ABI-violating x87 state.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All musl users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-libs/musl-1.1.24"
</code>
</resolution>
