K18549143:OpenSSL vulnerability CVE-2019-1559

Security Advisory

Original Publication Date: 20 Mar, 2019

Latest   Publication Date: 04 Apr, 2019

Security Advisory Description

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. In order for this to be exploitable
"non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised
implementations of certain commonly used ciphersuites. Also the application
must call SSL_shutdown() twice even if a protocol error has occurred
(applications should not do this but some do anyway). Fixed in OpenSSL 1.0.2r
(Affected 1.0.2-1.0.2q). (CVE-2019-1559)

Impact

This vulnerability may allow an attacker to disrupt service.

Security Advisory Status

F5 Product Development has assigned IDs 761725 and 765053 (BIG-IP and
Enterprise Manager), and CPF-25069 and CPF-25070 (Traffix) to this
