Updated openssl packages fix security vulnerabilities

OpenSSL 1.0.2 starting from version 1.0.2b introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the...

Carry Propagation

OpenSSL is vulnerable to a carry propagation issue with the x8664 Montgomery squaring procedure. This attack can be carried out against unpatched systems using a target private key with persistent DH parameters and a private key which is shared with multiple clients. This could in some...

UBUNTU-CVE-2017-3736

There is a carry propagating bug in the x8664 Montgomery squaring procedure in OpenSSL before 1.0.2m and 1.1.0 before 1.1.0g. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely...
