openssh/openssh-7.7p1-seccomp_ipc_flock.patch
Antonio Larrosa da2c6cc517 - Update to openssh 9.8p1:
* No changes for askpass, see main package changelog for
    details.

- Fix a dbus connection leaked in the logind patch that was
  missing a sd_bus_unref call (found by Matthias Gerstner):
  * logind_set_tty.patch
- Add a patch that fixes a small memory leak when parsing the
  subsystem configuration option:
  * fix-memleak-in-process_server_config_line_depth.patch

- Update to openssh 9.8p1:
  = Security
  * 1) Race condition in sshd(8) (bsc#1226642, CVE-2024-6387).
    A critical vulnerability in sshd(8) was present in Portable
    OpenSSH versions between 8.5p1 and 9.7p1 (inclusive) that may
    allow arbitrary code execution with root privileges.
    Successful exploitation has been demonstrated on 32-bit
    Linux/glibc systems with ASLR. Under lab conditions, the attack
    requires on average 6-8 hours of continuous connections up to
    the maximum the server will accept. Exploitation on 64-bit
    systems is believed to be possible but has not been
    demonstrated at this time. It's likely that these attacks will
    be improved upon.
    Exploitation on non-glibc systems is conceivable but has not
    been examined. Systems that lack ASLR or users of downstream
    Linux distributions that have modified OpenSSH to disable
    per-connection ASLR re-randomisation (yes - this is a thing, no
    - we don't understand why) may potentially have an easier path
    to exploitation. OpenBSD is not vulnerable.

Patch from IBM enabling the use of OpenCryptoki, submitted upstreams:
From: Eduardo Barretto <ebarretto@linux.vnet.ibm.com>

Subject: [PATCH 1/3] Allow flock and ipc syscall for s390 architecture
Date: Tue, 9 May 2017 14:27:13 -0300
In order to use the OpenSSL-ibmpkcs11 engine it is needed to allow flock
and ipc calls, because this engine calls OpenCryptoki (a PKCS#11
implementation) which calls the libraries that will communicate with the
crypto cards. OpenCryptoki makes use of flock and ipc and, as of now,
this is only need on s390 architecture.
