rar vulnerabilities ====================================================================== ====

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

Several security issues were fixed in RAR.

Software Description:
- rar: Archiver for .rar files

Details:

It was discovered that RAR incorrectly handled certain paths. If a
user or automated system were tricked into extracting a specially
crafted RAR archive, a remote attacker could possibly use this issue
to write arbitrary files outside of the targeted directory. (CVE-2022-30333)

It was discovered that RAR incorrectly handled certain recovery
volumes. If a user or automated system were tricked into extracting a specially crafted RAR archive, a remote attacker could possibly use
this issue to execute arbitrary code. (CVE-2023-40477)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 22.04 LTS
rar 2:6.23-1~22.04.1

Ubuntu 20.04 LTS
rar 2:6.23-1~20.04.1

This update uses a new upstream release, which includes additional bug fixes. In general, a standard system update will make all the
necessary changes.

I'm a registered user of RAR but I quit using it for BBS files since it's not backwards-compatible. I was using the open-source ARJ as I find it to be more capable than RAR or ZIP, but enough perople have bitched at me about using ARJ I'm just going to use Info-Zip's ZIP. I don't really like using ZIP as it was originally based on a stolen copy of the source code to ARC.

I am also a registered user, but don't use it. Not even sure if the keyfile is used under Linux. Never knew that about info-zip

Oh, it's the actual ZIP code by Phil Katz. If anything, Info-ZIP is its original code based on reverse engineering ZIP packets.

Here's one of the videos I watched on YT that explains how ZIP came to be
and how the BBS community embraced it based on Katz's lies: https://www.youtube.com/watch?v=lu7sY1LOWiI

I also did some fact-checking of my own and sadly, the video seems to be
spot on.

That was very interesting. And such a sad end for Katz.
