As described in the announcement, this fixes a security issue:
There is one security fix in this release:
- Fix for a newly discovered security issue known as the 'Terrapin'
attack, also numbered CVE-2023-48795. The issue affects widely-used
OpenSSH extensions to the SSH protocol: the ChaCha20+Poly1305
cipher system, and 'encrypt-then-MAC' mode.
In order to benefit from the fix, you must be using a fixed version
of PuTTY _and_ a server with the fix, so that they can agree to
adopt a modified version of the protocol. Alternatively, you may be
able to reconfigure PuTTY to avoid selecting any of the affected
modes.
If PuTTY 0.80 connects to an SSH server without the fix, it will
warn you if the initial protocol negotiation chooses an insecure
mode to run the connection in, so that you can abandon the
connection. If it's possible to alter PuTTY's configuration to
avoid the problem, then the warning message will tell you how to do
it.

5 CVEs affecting glibc according to the NVD database are considered as
not being security issues by upstream glibc developers:
* CVE-2010-4756: The glob implementation in the GNU C Library (aka
glibc or libc6) allows remote authenticated users to cause a denial
of service (CPU and memory consumption) via crafted glob expressions
that do not match any pathnames. glibc maintainers position: "That's
standard POSIX behaviour implemented by (e)glibc. Applications using
glob need to impose limits for themselves"
* CVE-2019-1010022: GNU Libc current is affected by: Mitigation
bypass. The impact is: Attacker may bypass stack guard
protection. The component is: nptl. The attack vector is: Exploit
stack buffer overflow vulnerability and use this bypass
vulnerability to bypass stack guard. NOTE: Upstream comments
indicate "this is being treated as a non-security bug and no real
threat. glibc maintainers position: "Not treated as a security issue
by upstream https://sourceware.org/bugzilla/show_bug.cgi?id=22850"
* CVE-2019-1010023: GNU Libc current is affected by: Re-mapping
current loaded library with malicious ELF file. The impact is: In
worst case attacker may evaluate privileges. The component is:
libld. The attack vector is: Attacker sends 2 ELF files to victim
and asks to run ldd on it. ldd execute code. NOTE: Upstream comments
indicate "this is being treated as a non-security bug and no real
threat. glibc maintainers position: "Not treated as a security issue
by upstream https://sourceware.org/bugzilla/show_bug.cgi?id=22851"
* CVE-2019-1010024: GNU Libc current is affected by: Mitigation
bypass. The impact is: Attacker may bypass ASLR using cache of
thread stack and heap. The component is: glibc. NOTE: Upstream
comments indicate "this is being treated as a non-security bug and
no real threat. glibc maintainers position: "Not treated as a
security issue by upstream
https://sourceware.org/bugzilla/show_bug.cgi?id=22852"
* CVE-2019-1010025: GNU Libc current is affected by: Mitigation
bypass. The impact is: Attacker may guess the heap addresses of
pthread_created thread. The component is: glibc. NOTE: the vendor's
position is "ASLR bypass itself is not a vulnerability. Glibc
maintainers position: "Not treated as a security issue by upstream
https://sourceware.org/bugzilla/show_bug.cgi?id=22853"

As reported in bug 15895, the GLIBC_VERSION field having a value
looking like 2.38-27-g750a45a783906a19591fb8ff6b7841470f1f5701, it
prevents the CPE/CVE matching with the NVD database to work correctly.
This commit fixes that by defining GLIBC_CPE_ID_VERSION, derived from
GLIBC_VERSION, by extracting the base version.
Also, we update GLIBC_IGNORE_CVES to account for the CVEs that have
clearly been fixed between 2.38 and
2.38-27-g750a45a783906a19591fb8ff6b7841470f1f5701. There are a number
of other CVEs still affecting the glibc package, but they are not
related to this
2.38...2.38-27-g750a45a783906a19591fb8ff6b7841470f1f5701 range.

OpenSSH 9.6 was released on 2023-12-18.
This release contains fixes for a newly-discovered weakness in the
SSH transport protocol (the "Terrapin" attack), a logic error relating
to constrained PKCS#11 keys in ssh-agent(1) and countermeasures for
programs that invoke ssh(1) with user or hostnames containing invalid
characters.

linux-pam is required to login via OpenSSH if the upstream refpolicy for
SELinux is enaabled, as linux-pam handles changing user contexts. If a
user wants to make their own policy and use a refpolicy via git, we of course
should let them do so. As such, only select linux-pam if the upstream version
of refpolicy is selected.

Since the update of Python to version 3.11 in commit
738500c296 ("package/python3: bump to
version 3.11.0"), python-sip fails to compile with:
siplib.c: In function ‘sip_api_get_frame’:
siplib.c:13750:22: error: invalid use of undefined type ‘struct _frame’
13750 | frame = frame->f_back;
This is due to a change in the Python C API, which is fixed by a new
patch. The patch can't be upstreamed, as SIP 4.x is no longer
maintained upstream.

rsync is used in the infrastructure, mostly for the per-package infra,
and for the override-srcdir mechanism, but also to build the manual.
As such, it is not optional but mandatory, and already listed so.
Drop the reference to rsync from the list of optional packages.
