Description Riccardo Schirone 2019-10-04 15:16:56 UTC
A memory leak was discovered in NetworkPkg/ArpDxe in function ArpOnFrameRcvdDpc(), because of an error condition that is not correctly handled and does not signal the recycleEvent signal before continuing the reception of packets. An attacker can use this flaw to cause memory exhaustion.

Fixed in upstream commit 65c73df44c61 ("ShellPkg: Fix 'ping' command Ip4 receive flow.", 2020-04-01).

> - TianoCore#2174:

A patch was upstreamed 9c20342eed70 ("NetworkPkg/Ip6Dxe: Improve Neightbor Discovery message validation.", 2020-03-30), but it caused a regression, which I subsequently reported. The fix for the regression (also tested OK by me) is pending subsys maintainer review.

Hi Laszlo:

I am not sure if this bug only need I do the sanity test of ovmf,or need more test about it? could you provide me some suggestions.Many thanks!

Comment 16 Laszlo Ersek 2020-07-02 11:45:30 UTC
Hello Leidong Wang,

thanks for the question.

TianoCore Bugzillas 1610, 2031 and 2032 were all found with network fuzzing; we don't have a reproducer.

TianoCore #2174 does not say if it had been found with a fuzzer or not, but we still have no reproducer.

So the above indicate that sanity testing should be sufficient.

The fix for TianoCore#2174 introduced a regression however (up-stream); that one was fixed under TianoCore#2655. This suggests a more directed sanity testing in turn, namely an IPv6 netboot test.

So please sanity check IPv4 and IPv6 PXE boot.

Thanks!

Hi Laszlo,

thanks for your reply! ! !

OVMF sanity test, IPv4 boot and IPv6 boot can work normally.

Thank you!
