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.
