Ubuntu 15.10 : openssl vulnerability (USN-2883-1)

Antonio Sanso discovered that OpenSSL reused the same private DH exponent for the life of a server process when configured with a X9.42 style parameter file. This could allow a remote attacker to possibly discover the server's private DH exponent when being used with non-safe primes. Note that...

CVE-2016-0701

The DHcheckpubkey function in crypto/dh/dhcheck.c in OpenSSL 1.0.2 before 1.0.2f does not ensure that prime numbers are appropriate for Diffie-Hellman DH key exchange, which makes it easier for remote attackers to discover a private DH exponent by making multiple handshakes with a peer that chose...

Vulnerability in OpenSSL - DH small subgroups

Historically OpenSSL usually only ever generated DH parameters based on “safe” primes. More recently in version 1.0.2 support was provided for generating X9.42 style parameter files such as those required for RFC 5114 support. The primes used in such files may not be “safe”. Where an application ...
