Categoría:	Mageia Linux Local Security Checks
Título:	Mageia: Security Advisory (MGASA-2015-0152)
Resumen:	The remote host is missing an update for the 'ntp' package(s) announced via the MGASA-2015-0152 advisory.
Descripción:	Summary: The remote host is missing an update for the 'ntp' package(s) announced via the MGASA-2015-0152 advisory. Vulnerability Insight: Updated ntp packages fix security vulnerabilities: The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP before 4.2.8p2 requires a correct MAC only if the MAC field has a nonzero length, which makes it easier for man-in-the-middle attackers to spoof packets by omitting the MAC (CVE-2015-1798). The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in-the-middle attackers to cause a denial of service (synchronization loss) by spoofing the source IP address of a peer (CVE-2015-1799). Affected Software/OS: 'ntp' package(s) on Mageia 4. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:A/AC:M/Au:N/C:N/I:P/A:P
