WP Engine Reprieve

Read Time:59 Second

I’ve heard from WP Engine customers that they are frustrated that WP Engine hasn’t been able to make updates, plugin directory, theme directory, and Openverse work on their sites. It saddens me that they’ve been negatively impacted by Silver Lake‘s commercial decisions.

On WP Engine’s homepage, they promise “Unmatched performance, automated updates, and bulletproof security ensure your sites thrive.”

WP Engine was well aware that we could remove access when they chose to ignore our efforts to resolve our differences and enter into a commercial licensing agreement. Heather Brunner, Lee Wittlinger, and their Board chose to take this risk. WPE was also aware that they were placing this risk directly on WPE customers. You could assume that WPE has a workaround ready, or they were simply reckless in supporting their customers. Silver Lake and WP Engine put their customers at risk, not me.

We have lifted the blocks of their servers from accessing ours, until October 1, UTC 00:00. Hopefully this helps them spin up their mirrors of all of WordPress.org’s resources that they were using for free while not paying, and making legal threats against us.

Multiple Vulnerabilities in Foxit PDF Reader and Editor Could Allow for Arbitrary Code Execution

Read Time:35 Second

Multiple vulnerabilities have been discovered in Foxit PDF Reader and Editor, the most severe of which could result in arbitrary code execution. Foxit PDF Reader is a multilingual freemium PDF tool that can create, view, edit, digitally sign, and print PDF files. Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

FEDORA-2024-d940f25a53

Packages in this update:

aws-2020-12.1.fc39

Update description:

CVE-2024-41708: Ada Web Server did not use a cryptographically secure pseudorandom number generator.

AWS.Utils.Random and AWS.Utils.Random_String used Ada.Numerics.Discrete_Random, which is not designed to be cryptographically secure. Random_String also introduced a bias in the generated pseudorandom string values, where the values “1” and “2” had a much higher frequency than any other character.

The internal state of the Mersenne Twister PRNG could be revealed, and lead to a session hijacking attack.

This update fixes the problem by using /dev/urandom instead of Discrete_Random.
