Descripción:	Summary: The remote host is missing an update for the 'gnutls' package(s) announced via the MGASA-2018-0435 advisory. Vulnerability Insight: The updated packages fix security vulnerabilities: It was found that the GnuTLS implementation of HMAC-SHA-256 and HMAC-SHA-384 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data using crafted packets (CVE-2018-10844, CVE-2018-10845). A cache-based side channel in GnuTLS implementation that leads to plain text recovery in cross-VM attack setting was found. An attacker could use a combination of 'Just in Time' Prime+probe attack in combination with Lucky-13 attack to recover plain text using crafted packets (CVE-2018-10846). Affected Software/OS: 'gnutls' package(s) on Mageia 6. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:N/A:N
