Updated libgcrypt packages fix security vulnerability: Daniel Genkin, Lev Pachmanov, Itamar Pipman and Eran Tromer discovered that the ECDH secret decryption keys in applications using the libgcrypt20 library could be leaked via a side-channel attack (CVE-2015-7511). The libgcrypt package was also updated to include countermeasures against Lenstra's fault attack on RSA Chinese Remainder Theorem optimization in RSA. A signature verification step was updated to protect against leaks of private keys in case of hardware faults or implementation errors in numeric libraries. This issue is equivalent to the CVE-2015-5738 issue in gnupg.
