3. Description:
OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and
Transport Layer Security (TLS) protocols, as well as a full-strength
general-purpose cryptography library.
Security Fix(es):
* openssl: ROHNP - Key Extraction Side Channel in Multiple Crypto Libraries
(CVE-2018-0495)
* openssl: Malicious server can send large prime to client during DH(E) TLS
handshake causing the client to hang (CVE-2018-0732)
* openssl: Handling of crafted recursive ASN.1 structures can cause a stack
overflow and resulting denial of service (CVE-2018-0739)
* openssl: Malformed X.509 IPAdressFamily could cause OOB read
(CVE-2017-3735)
* openssl: RSA key generation cache timing vulnerability in
crypto/rsa/rsa_gen.c allows attackers to recover private keys
(CVE-2018-0737)
For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.
Additional Changes:
For detailed information on changes in this release, see the Red Hat
Enterprise Linux 7.6 Release Notes linked from the References section.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
For the update to take effect, all services linked to the OpenSSL library
must be restarted, or the system rebooted.
