It was discovered that libXdmcp was generating weak session keys.
A local attacker could possibly use this issue to perform a brute
force attack and obtain another user’s key.

MVPower CCTV DVR models, including TV-7104HE 1.8.4 115215B9 and TV7108HE, contain a web shell that is accessible via a /shell URI. A remote unauthenticated attacker can execute arbitrary operating system commands as root. This vulnerability has also been referred to as the “JAWS webserver RCE” because of the easily identifying HTTP response server field. Other firmware versions, at least from 2014 through 2019, can be affected. This was exploited in the wild in 2017 through 2022.

Update description:

Upstream update including security & bug fixes as well as feature enhancements.

From the upstream release notes:

CVE-2022-39253

When relying on the –local clone optimization, Git dereferences
symbolic links in the source repository before creating hardlinks
(or copies) of the dereferenced link in the destination repository.
This can lead to surprising behavior where arbitrary files are
present in a repository’s $GIT_DIR when cloning from a malicious
repository.

Git will no longer dereference symbolic links via the –local
clone mechanism, and will instead refuse to clone repositories that
have symbolic links present in the $GIT_DIR/objects directory.

Additionally, the value of protocol.file.allow is changed to be
“user” by default.

CVE-2022-39260

An overly-long command string given to git shell can result in
overflow in split_cmdline(), leading to arbitrary heap writes and
remote code execution when git shell is exposed and the directory
$HOME/git-shell-commands exists.

git shell is taught to refuse interactive commands that are
longer than 4MiB in size. split_cmdline() is hardened to reject
inputs larger than 2GiB.
