• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Hans de Graaff 2023-03-31 07:09:47 UTC]

https://www.ruby-lang.org/en/news/2023/03/30/redos-in-time-cve-2023-28756/

We have released the time gem version 0.1.1 and 0.2.2 that has a security fix for a ReDoS vulnerability. This vulnerability has been assigned the CVE identifier CVE-2023-28756.
Details

The Time parser mishandles invalid strings that have specific characters. It causes an increase in execution time for parsing strings to Time objects.

A ReDoS issue was discovered in the Time gem 0.1.0 and 0.2.1 and Time library of Ruby 2.7.7.


https://www.ruby-lang.org/en/news/2023/03/28/redos-in-uri-cve-2023-28755/

We have released the uri gem version 0.12.1, 0.11.1, 0.10.2 and 0.10.0.1 that has a security fix for a ReDoS vulnerability. This vulnerability has been assigned the CVE identifier CVE-2023-28755.
Details

A ReDoS issue was discovered in the URI component. The URI parser mishandles invalid URLs that have specific characters. It causes an increase in execution time for parsing strings to URI objects.

The uri gem version 0.12.0, 0.11.0, 0.10.1, 0.10.0 and all versions prior 0.10.0 are vulnerable for this vulnerability.

[Comment 1 Hans de Graaff 2023-03-31 07:11:42 UTC]

Fixed in ruby 2.7.8, ruby 3.0.6, ruby 3.1.4 and ruby 3.2.2, and in dev-ruby/time-0.2.2.

URI is only shipped bundled with dev-lang/ruby at the moment.

Given that upstream likes to mix in other fixes with security updates I'd like to wait a couple of days before filing a stable bug.

Cleanup done.

Not for 2.7.x?

That version was already masked for removal, IIRC.
