Security update for libgcrypt

This update fixes the following issues:

  • Use ciphertext blinding for Elgamal decryption [CVE-2014-3591]. See http://www.cs.tau.ac.il/~tromer/radioexp/ for details. (bsc#920057)
  • Fixed data-dependent timing variations in modular exponentiation [related to CVE-2015-0837, Last-Level Cache Side-Channel Attacks are Practical]

Описание

Libgcrypt before 1.6.3 and GnuPG before 1.4.19 does not implement ciphertext blinding for Elgamal decryption, which allows physically proximate attackers to obtain the server's private key by determining factors using crafted ciphertext and the fluctuations in the electromagnetic field during multiplication.

Описание

The mpi_powm function in Libgcrypt before 1.6.3 and GnuPG before 1.4.19 allows attackers to obtain sensitive information by leveraging timing differences when accessing a pre-computed table during modular exponentiation, related to a "Last-Level Cache Side-Channel Attack."
