Hi there, A few days ago, I wrote a blog post about CVEs. It was my first time looking at CVEs closely. Then I came across a reddit post discussing CVE-2024-56406. I am a bit confused, was this fixed in Perl v5.38.4 or Perl v5.40.2? That said, it gave me something fun to dig into. I already know what I'll be doing next. During my search, I discovered the, CPAN Security Group, a community effort dedicated to handling security incidents on CPAN. Pretty cool! Also the Perl Toolchain Summit 2025 needs our support as mentioned in the blog post. I'm happy to see my current employer, Oleeo, listed as one of the In-Kind Sponsors. Now, I'm curious to find out who the lucky team member is that gets to attend!. It's happening this year from Thursday May 1st to Sunday May 4th 2025. I remember back in 2019, the summit was held so close to me, in Marlow, if I recall correctly. I've said it before and I'll say it again, I have to get involved in the MetaCPAN project. The main blocker last time was setting up the local development environment. I spoke to someone about it, can't remember who, and he mentioned the team was working on simplifying the setup process to make it easier for contributors. I haven't had a chance to check the current status, but I'm adding it to my ever-growing TODO list. Happy Monday and enjoy the rest of the newsletter! Mohammad Sajid Anwar |
