        "Description": "This update upgrades libgcrypt to version 1.7.8-alt1.S1. \nSecurity Fix(es):\n\n * BDU:2018-00007: Уязвимость библиотеки libgcrypt11, связанная с отсутствием защиты служебных данных, позволяющая нарушителю нарушить конфиденциальность данных\n\n * CVE-2017-7526: libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This side-channel requires that attacker can run arbitrary software on the hardware where the private RSA key is used.\n\n * CVE-2017-9526: In Libgcrypt before 1.7.7, an attacker who learns the EdDSA session key (from side-channel observation during the signing process) can easily recover the long-term secret key. 1.7.7 makes a cipher/ecc-eddsa.c change to store this session key in secure memory, to ensure that constant-time point operations are used in the MPI library.",
