[R] Regarding the Security Vulnerability CVE 2024 - 27322

[Priya, Aishwarya]

Hi Ivan and R - Help Team,

Thank you for your prompt response and the helpful information.

I have another query: Is there a way to patch or upgrade the existing installation to version 4.4.0, rather than having to uninstall the older version and then install the latest one? A direct upgrade or patch would greatly simplify the process and reduce downtime.

Your guidance on this matter would be greatly appreciated.

Thank you once again for your assistance.

Thanks & Regards,

What's your threat model?

If you need the CVE fix purely because you are required to install it by some sort of regulations, installing R-4.4.0 and removing all older versions of R is definitely the right thing to do.

If you actually need to be secure against untrusted *.rds or *.rda files, R-4.4.0 or any other version of R will be of no help to you.
There are too many ways to make an R object dangerous to use, and the *.rds and *.rda files will faithfully represent the trapped R object even in the absence of any vulnerabilities in the parser:

If you only process *.rds and *.rda files you trust, you've never been in danger from this so-called vulnerability. Feel free to keep running older versions of R.
