        "Description": "This update upgrades libgcrypt to version 1.8.5-alt3. \nSecurity Fix(es):\n\n * BDU:2020-01727: Уязвимость криптографической библиотеки Python ECDSA, связанная с недостаточной обработкой исключительных состояний, позволяющая нарушителю вызвать отказ в обслуживании\n\n * CVE-2019-12904: In Libgcrypt 1.8.4, the C implementation of AES is vulnerable to a flush-and-reload side-channel attack because physical addresses are available to other processes. (The C implementation is used on platforms where an assembly-language implementation is unavailable.) NOTE: the vendor's position is that the issue report cannot be validated because there is no description of an attack\n\n * CVE-2019-13627: It was discovered that there was a ECDSA timing attack in the libgcrypt20 cryptographic library. Version affected: 1.8.4-5, 1.7.6-2+deb9u3, and 1.6.3-2+deb8u4. Versions fixed: 1.8.5-2 and 1.6.3-2+deb8u7.",
