FreeBSD : QtNetworkAuth -- predictable seeding of PRNG in QAbstractOAuth (f5fa174d-19de-11ef-83d8-4ccc6adda413)

critical Nessus Plugin ID 197922



The remote FreeBSD host is missing one or more security-related updates.


The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the f5fa174d-19de-11ef-83d8-4ccc6adda413 advisory.

Andy Shaw reports:
The OAuth1 implementation in QtNetworkAuth created nonces using a PRNG that was seeded with a predictable seed.
This means that an attacker that can somehow control the time of the first OAuth1 flow of the process has a high chance of predicting the nonce used in said OAuth flow.

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

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


Update the affected packages.
