-------------------------------------------------------------------------------- Fedora Update Notification FEDORA-2024-63f98f8c60 2024-10-06 02:10:55.593602 -------------------------------------------------------------------------------- Name : aws Product : Fedora 40 Version : 2020 Release : 16.1.fc40 URL : http://libre.adacore.com/tools/aws Summary : Ada Web Server Description : AWS is a complete framework to develop Web based applications. The main part of the framework is the embedded Web server. This small yet powerful Web server can be embedded into your application so your application will be able to talk with a standard Web browser Around this Web server a lot of services have been developed. -------------------------------------------------------------------------------- Update Information: 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.
