SeaCat Technology and the Latest OpenSSL Update (1.1.0d, 1.0.2k)

Thursday, January 26, 2017

OpenSSL released a new version on 26 January 2017. The new release fixed one low-severity issue and three moderate ones:

  • Truncated packet could crash via OOB read (CVE-2017-3731)
  • Bad (EC)DHE parameters cause a client crash (CVE-2017-3730)
  • BN_mod_exp may produce incorrect results on x86_64 (CVE-2017-3732)
  • Montgomery multiplication may produce incorrect results (CVE-2016-7055)

Except for the (EC)DHE parameter-related issue, all mentioned issues relates to functionalities that are never used by SeaCat technology. An attack based CVE-2017-3730 affects only the client side of the communication. A successful attack results in a client crash during the beginning of a negotiation process. Attackers have to have the data communication under control to be able to send specially crafted packets.

Recommendation:

We recommend you to update to the latest version of SeaCat client. If you have any question, please contact support@teskalabs.com. Alternatively, look at our documentation to know more about SeaCat application security technology.
