Writing into /dev/urandom doesn't actually credit any entropy bits. And
while it adds that data to the entropy pool, it won't actually be
immediately used when reading from /dev/urandom subsequently. This is
how the kernel's /dev/urandom has always worked, unfortunately.
As a result of this behavior, which may be understandably surprising,
writing a good seed file into /dev/urandom and then saving a new seed
file immediately after is dangerous, because the new seed file may wind
up being entirely deterministic, even if the old seed file was quite
good.
This has been fixed in systemd with
<da2862ef06>,
and fortunately it's possible to do the same thing in shell script here.
Specifically, instead of just saving new /dev/urandom output straight
up, we hash the new /dev/urandom together with the old seed, in order to
produce the new seed. This way the amount of entropy in the new seed
will stay the same or get better, but not appreciably regress.
At the same time, the pool size check in this script is useless. Writing
to /dev/urandom never credits bits anyway, so no matter what, writing
into /dev/urandom is useful and not harmful. There's also not much of a
point in seeding with more than 256 bits, which is what the hashing
operation above produces. So this commit removes the file size check.
As a final note, while this commit improves upon the status quo by
removing a vulnerability, this shell script still does not actually
initialize the RNG like it says it does. For initialization via a seed
file, the RNDADDENTROPY ioctl must be used but there's currently no way
to do that from a shell script for now.

Fix CVE-2022-21716: Twisted is an event-based framework for internet
applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH
client and server implement is able to accept an infinite amount of data
for the peer's SSH version identifier. This ends up with a buffer using
all the available memory. The attach is a simple as `nc -rv localhost 22
< /dev/zero`. A patch is available in version 22.2.0. There are
currently no known workarounds.

Fix CVE-2022-26495: In nbd-server in nbd before 3.24, there is an
integer overflow with a resultant heap-based buffer overflow. A value of
0xffffffff in the name length field will cause a zero-sized buffer to be
allocated for the name, resulting in a write to a dangling pointer. This
issue exists for the NBD_OPT_INFO, NBD_OPT_GO, and NBD_OPT_EXPORT_NAME
messages.
Fix CVE-2022-26496: In nbd-server in nbd before 3.24, there is a
stack-based buffer overflow. An attacker can cause a buffer overflow in
the parsing of the name field by sending a crafted NBD_OPT_INFO or
NBD_OPT_GO message with an large value as the length of the name.

Commit 73ce754531 in master added the

This commit was backported as fad154253d
in the LTS 2021.02.x branch, but this branch does not have the
libqrtr-glib package, as it was added after 2021.02.
Due to this, the DEVELOPERS file is bogus in 2021.02.x, which causes
the following warning when running pkg-stats:

Fix CVE-2022-24128: Timescale TimescaleDB 1.x and 2.x before 2.5.2 may
allow privilege escalation during extension installation. The
installation process uses commands such as CREATE x IF NOT EXIST that
allow an unprivileged user to precreate objects. These objects will be
used by the installer (which executes as Superuser), leading to
privilege escalation. In order to be able to take advantage of this, an
unprivileged user would need to be able to create objects in a database
and then get a Superuser to install TimescaleDB into their database. (In
the fixed versions, the installation aborts when it finds that an object
already exists.)

The check_package_get_latest_version_by_distro() function analyzes the
data returned by release-monitoring.org. For two of our
packages (bento4 and qextserialport), release-monitoring.org returns
something that is a bit odd: it returns an entry with a
"stable_versions" field that contains an empty array. Our code was
ready to have or not have a "stable_versions" entry, but when it is
present, we assumed it was not an empty array. These two packages, for
some reason, break this assumption.
In order to solve this problem, this commit is more careful, and uses
the stable_versions field only if it exists and it has at least one
entry. The code is also reworked as a sequence of "if...elif...else"
to be more readable.
This fixes the following exception when running pkg-stats on the full
package set:

Changes between 1.1.1m and 1.1.1n [15 Mar 2022]
*) Fixed a bug in the BN_mod_sqrt() function that can cause it to loop forever
for non-prime moduli.
Internally this function is used when parsing certificates that contain
elliptic curve public keys in compressed form or explicit elliptic curve
parameters with a base point encoded in compressed form.
It is possible to trigger the infinite loop by crafting a certificate that
has invalid explicit curve parameters.
Since certificate parsing happens prior to verification of the certificate
signature, any process that parses an externally supplied certificate may
thus be subject to a denial of service attack. The infinite loop can also
be reached when parsing crafted private keys as they can contain explicit
elliptic curve parameters.
Thus vulnerable situations include:
- TLS clients consuming server certificates
- TLS servers consuming client certificates
- Hosting providers taking certificates or private keys from customers
- Certificate authorities parsing certification requests from subscribers
- Anything else which parses ASN.1 elliptic curve parameters
Also any other applications that use the BN_mod_sqrt() where the attacker
can control the parameter values are vulnerable to this DoS issue.
