Categoría:	Mageia Linux Local Security Checks
Título:	Mageia: Security Advisory (MGASA-2015-0163)
Resumen:	The remote host is missing an update for the 'chrony' package(s) announced via the MGASA-2015-0163 advisory.
Descripción:	Summary: The remote host is missing an update for the 'chrony' package(s) announced via the MGASA-2015-0163 advisory. Vulnerability Insight: Updated chrony package fixes security vulnerabilities: Using particular address/subnet pairs when configuring access control would cause an invalid memory write. This could allow attackers to cause a denial of service (crash) or execute arbitrary code (CVE-2015-1821). When allocating memory to save unacknowledged replies to authenticated command requests, a pointer would be left uninitialized, which could trigger an invalid memory write. This could allow attackers to cause a denial of service (crash) or execute arbitrary code (CVE-2015-1822). When peering with other NTP hosts using authenticated symmetric association, the internal state variables would be updated before the MAC of the NTP messages was validated. This could allow a remote attacker to cause a denial of service by impeding synchronization between NTP peers (CVE-2015-1853). Affected Software/OS: 'chrony' package(s) on Mageia 4. Solution: Please install the updated package(s). CVSS Score: 6.5 CVSS Vector: AV:N/AC:L/Au:S/C:P/I:P/A:P
