K43570545:OpenSSL vulnerability CVE-2016-7055
Security Advisory
Original Publication Date: 04 Feb, 2017
Latest Publication Date: 02 Mar, 2019
Security Advisory Description
There is a carry propagating bug in the Broadwell-specific Montgomery
multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles
input lengths divisible by, but longer than 256 bits. Analysis suggests that
attacks against RSA, DSA and DH private keys are impossible. This is because
the subroutine in question is not used in operations with the private key
itself and an input of the attacker's direct choice. Otherwise the bug can
manifest itself as transient authentication and key negotiation failures or
reproducible erroneous outcome of public-key operations with specially crafted
input. Among EC algorithms only Brainpool P-512 curves are affected and one
presumably can attack ECDH key negotiation. Impact was not analyzed in detail,
because pre-requisites for attack are considered unlikely. Namely multiple
clients have to choose the curve in question and the server has to share the
private key among them, neither of which is default behaviour. Even then only
clients that chose the curve will be affected. (CVE-2016-7055)
Impact
Due to the high complexity of this attack, impact is considered minimal. For
more information, refer to OpenSSL Security Advisory [10 Nov 2016].

^1 The specified products contain the affected code. However, F5 identifies the
vulnerability status as Not vulnerable because the attacker cannot exploit the
code in default, standard, or recommended configurations.
Security Advisory Recommended Actions
If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.
