CVE-2018-0734

TITLE

OpenSSL Encryption problem vulnerability

DESCRIPTION

The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key. Fixed in OpenSSL 1.1.1a (Affected 1.1.1). Fixed in OpenSSL 1.1.0j (Affected 1.1.0-1.1.0i). Fixed in OpenSSL 1.0.2q (Affected 1.0.2-1.0.2p). The product supports a variety of encryption algorithms, including symmetric ciphers, hash algorithms, secure hash algorithms, etc. The vulnerability stems from incorrect use of relevant cryptographic algorithms by network systems or products, resulting in improperly encrypted content, weak encryption, and storing sensitive information in plain text. Here are the details from the Slackware 14.2 ChangeLog: +--------------------------+ patches/packages/openssl-1.0.2q-i586-1_slack14.2.txz: Upgraded.
