An out-of-bounds read vulnerability was found in the SLiRP networking
implementation of the QEMU emulator. This flaw occurs in the
icmp6_send_echoreply() routine while replying to an ICMP echo request,
also known as ping. This flaw allows a malicious guest to leak the
contents of the host memory, resulting in possible information disclosure.
This flaw affects versions of libslirp before 4.3.1.
