Título:	CentOS Update for ntp CESA-2009:0046 centos5 i386
Resumen:	The remote host is missing an update for the 'ntp'; package(s) announced via the referenced advisory.
Descripción:	Summary: The remote host is missing an update for the 'ntp' package(s) announced via the referenced advisory. Vulnerability Insight: The Network Time Protocol (NTP) is used to synchronize a computer's time with a referenced time source. A flaw was discovered in the way the ntpd daemon checked the return value of the OpenSSL EVP_VerifyFinal function. On systems using NTPv4 authentication, this could lead to an incorrect verification of cryptographic signatures, allowing time-spoofing attacks. (CVE-2009-0021) Note: This issue only affects systems that have enabled NTP authentication. By default, NTP authentication is not enabled. All ntp users are advised to upgrade to the updated packages, which contain a backported patch to resolve this issue. After installing the update, the ntpd daemon will restart automatically. Affected Software/OS: ntp on CentOS 5 Solution: Please install the updated packages. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
