Hi,

The following vulnerability was published for texlive-bin.

CVE-2023-32668[0]:
| LuaTeX before 1.17.0 allows a document (compiled with the default
| settings) to make arbitrary network requests. This occurs because full
| access to the socket library is permitted by default, as stated in the
| documentation. This also affects TeX Live before 2023 r66984 and
| MiKTeX before 23.5.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.

Please adjust the affected versions in the BTS as needed.

Salvatore

I updated to luatex 1.17.0 already in the TeX Live binaries for TL 2023 
in commit 5348a805847c038d92c80a9b208da48dc527decd, the needed adaptions 
for Context were made, but all that needs to be tested.

Is that sufficient or do we need to fix all this in bookworm / bullseye too?

Correct, I think this is the correct way to address it for trixie. For
bookworm and bullseye, the impact is low enough that we can either
think of including the fix in a point release or ignore it. When
looking at it it was unclear to me apart ConTeXt, if any other reverse
depndencies might be impacted. According to
https://tug.org/~mseven/luatex.html#luasocket at least ConTeXt might
need change for the default change behviour with the new flag.

Thanks for taking care of this.

Salvatore
