FreeBSD : OpenSSL -- Padding oracle vulnerability (7700061f-34f7-11e9-b95c-b499baebfeaf)
Medium Nessus Plugin ID 122359
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionThe OpenSSL project reports :
0-byte record padding oracle (CVE-2019-1559) (Moderate) If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data.
SolutionUpdate the affected packages.
