If you use LibreOffice (as I do... almost all articles in this newsletter are composed in LibreOffice), you need to update your copy NOW.

Earlier this month, a security vulnerability in the popular libwebp software library was discovered, affecting everything from web browsers to email clients. The Document Foundation, the developers behind the free and open-source LibreOffice suite, has now released an emergency update for LibreOffice that includes the fix. You should update as soon as possible if you have LibreOffice installed.

The blog post explains, "The Document Foundation is releasing LibreOffice 7.6.2 Community and LibreOffice 7.5.7 Community ahead of schedule to address a security issue known as CVE 2023-4863, which originates in a widely used code library known as libwebp, created by Google more than a decade ago to render the then-new WebP graphics format. [...] All users of LibreOffice are encouraged to update their current version as soon as possible."

NOTE: I updated my copy and found it was a simple process. I suggest you update NOW.
