Several vulnerabilities were discovered in OpenSSL :

CVE-2016-7056

A local timing attack was discovered against ECDSA P-256.

CVE-2016-8610

It was discovered that no limit was imposed on alert packets during an SSL handshake.

CVE-2017-3731

Robert Swiecki discovered that the RC4-MD5 cipher when running on 32 bit systems could be forced into an out-of-bounds read, resulting in denial of service.

For Debian 7 'Wheezy', these problems have been fixed in version 1.0.1t-1+deb7u2.

We recommend that you upgrade your openssl packages.

This update for gnutls fixes the following issues :

  - Malformed asn1 definitions could cause a segmentation     fault in the asn1 definition parser (bsc#961491).

  - CVE-2016-8610: Remote denial of service in SSL alert     handling (bsc#1005879).

  - CVE-2017-5335: Decoding a specially crafted OpenPGP     certificate could have lead to heap and stack overflows     (bsc#1018832).

  - CVE-2017-5336: Decoding a specially crafted OpenPGP     certificate could have lead to heap and stack overflows     (bsc#1018832).

  - CVE-2017-5337: Decoding a specially crafted OpenPGP     certificate could have lead to heap and stack overflows     (bsc#1018832).

This update for gnutls fixes the following security issues :

  - GnuTLS could have crashed when processing maliciously     crafted OpenPGP certificates (GNUTLS-SA-2017-2,     bsc#1018832, CVE-2017-5335, CVE-2017-5337,     CVE-2017-5336)

  - GnuTLS could have falsely accepted certificates when     using OCSP (GNUTLS-SA-2016-3, bsc#999646, CVE-2016-7444)

  - GnuTLS could have suffered from 100% CPU load DoS     attacks by using SSL alert packets during the handshake     (bsc#1005879, CVE-2016-8610)

This update was imported from the SUSE:SLE-12:Update update project.

Minor upstream release fixing CVE-2016-8610, CVE-2017-3731, CVE-2017-3732.

A denial of service flaw was found in the way the TLS/SSL protocol defined

processing of ALERT packets during a connection handshake. A remote attacker

could use this flaw to make a TLS/SSL server consume an excessive amount of CPU

and fail to accept connections form other clients. (CVE-2016-8610)

Multiple flaws were found in the way gnutls processed OpenPGP certificates. An

attacker could create specially crafted OpenPGP certificates which, when parsed

by gnutls, would cause it to crash. (CVE-2017-5335 , CVE-2017-5336 ,

CVE-2017-5337)

The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2017-1298:01 advisory.

    The OpenSSL toolkit provides support for secure communications between     machines. OpenSSL includes a certificate management tool and shared     libraries which provide various cryptographic algorithms and     protocols.
    Security issues fixed with this release:

This update for openssl fixes the following issues :

Security issues fixed :

CVE-2018-0734: Fixed timing vulnerability in DSA signature generation (bsc#1113652).

CVE-2018-5407: Fixed elliptic curve scalar multiplication timing attack defenses (bsc#1113534).

CVE-2018-0737: Corrected the current error detection of the current fix (bsc#1106197).

CVE-2016-8610: Adjusted current fix and add missing error string (bsc#1110018).

Add missing timing side channel patch for DSA signature generation (bsc#1113742).

Fixed the 'One and Done' side-channel attack on RSA (bsc#1104789).

Non-security issues fixed: Added openssl(cli) so that the packages that required the openssl binary can require this instead of the new openssl meta package (bsc#1101470).
