Fedora 39 : aws (2024-d940f25a53)

high Nessus Plugin ID 208219

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 39 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2024-d940f25a53 advisory.

 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.

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected aws package.
