| Vector | AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N |
Name of the Vulnerable Software and Affected Versions
QEMU libslirp versions prior to 4.3.1
Description
An out-of-bounds read issue was found in the SLiRP networking implementation of the QEMU emulator. This occurs in the
icmp6 send echoreply() routine while replying to an ICMP echo request, also known as ping. This allows a malicious guest to leak the contents of the host memory, resulting in possible information disclosure.Recommendations
For versions of libslirp prior to 4.3.1, update to version 4.3.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the
icmp6 send echoreply() routine until a patch is available. Avoid using the SLiRP networking implementation in QEMU until the issue is resolved.Exploit
