    an application dependent impact.

  <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>

  <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 "&gt;=sys-libs/musl-1.1.24"
    </code>
