ID de Prueba:	1.3.6.1.4.1.25623.1.0.146236
Categoría:	Denial of Service
Título:	NTPd < 4.2.8p2, 4.3.x < 4.3.12 Keygen Vulnerability
Resumen:	NTPd is prone to a vulnerability in ntp-keygen.
Descripción:	Summary: NTPd is prone to a vulnerability in ntp-keygen. Vulnerability Insight: ntp-keygen does not generate MD5 keys with sufficient entropy on big endian machines when the lowest order byte of the temp variable is between 0x20 and 0x7f and not #, which might allow remote attackers to obtain the value of generated MD5 keys via a brute force attack with the 93 possible keys. Affected Software/OS: NTPd version prior to 4.2.8p2 and 4.3.x prior to 4.3.12. Solution: Update to version 4.2.8p2 or later. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
