Description Hu 2022-05-12 12:49:38 UTC
rh#2064604

A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem.

Comment 3 Michal Kubeček 2022-06-10 09:39:40 UTC
First thing, I don't understand the "memory leak" part at all.

Second, it's not really accurate to think about this in the terms of a bug
that has been introduced at some point. It's rather a continuing process of
improving the (ephemeral) source port selection algorithm.

In the old times, these were assigned incrementally, as well as e.g. TCP
initial sequence numbers or IP identifier (IPID) values. As the time went,
it was found that generating them in a deterministic way may make attackers'
life easier in some ways so deterministic increments were successively
replaced by small (pseudo)random increments, MD4 based hash algorithm,
MD5 based one, now siphash based one, ...

One thing to keep in mind is that we are not talking about a security bug
in the sense how the term is usually understood. An unprotected TCP connection
(i.e. one which does not use TLS and is not hidden behind IPsec or similar
protection) is never going to be secure. If we want an actual security, one
of the actual encryption and authentication mechanisms is necessary.

If I understand the series description correctly, the paper in question
describes an attack scheme which allows to "identify a client" by forcing
it to create ~10000 connections. It's not completely clear what exactly does
that mean but one thing is certain: it's not really a security bug in the
traditional sense.

I don't think we should consider backporting this new series into any branch
which does not have current "state of art" code: if we were OK with not so
perfect algorithm last time, there is no reason to change our minds now.
As for SLE12-SP5, SLE15-SP3 and SLE15-SP4, a backport probably makes sense
if it's not too intrusive (stable is not relevant, mainline already has the
series since 5.18).

In this case, should this bug be considered for livepatching?

About the "state of the art" code, do you mean SLE12-SP5, SLE15-SP3 and SLE15-SP4? Do we have a PoC for this problem? For know I didn't found any backport in cve/5.3 branch.

I don't think this issue is serious enough to qualify for livepatching.

> SLE15-SP4?

Yes.

> For know I didn't found any backport in cve/5.3 branch.

That's expected. As cve/linux-5.3 gets merged into all active 5.3 based
branches, any patch present in it would be also present in SLE15-SP2-LTSS.
But the previous siphash stuff was backported only into SLE15-SP3.
Comment 6 Marcus Meissner 2022-06-15 12:37:58 UTC
CVSS score rerated from access complexity: low -> high.
Comment 8 Michal Kubeček 2022-06-22 09:30:54 UTC
Forgot to update the bug: the series is now backported into all branches
which have the previous siphash stuff:

  stable        5.18-rc6
  SLE15-SP4     dbe5a4059988  (merged)
  SLE15-SP3     f0bb4ae16395  (merged)
  SLE12-SP5     8d93613e160d  (merged)

Reassigning back to security team.
