Média
| Vetor | AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
NTP versions 4.2.x through 4.2.8p3
NTP versions 4.3.x through 4.3.76
Description
The issue allows remote authenticated users to cause a denial of service, resulting in an infinite loop or crash, by pointing the key file at the log file. This is due to an ASSERT botch instead of returning FAIL on some invalid values by the decodenetnum() function. An attacker could exploit this to cause a denial of service.
Recommendations
For NTP versions 4.2.x through 4.2.8p3, update to version 4.2.8p4 or later.
For NTP versions 4.3.x through 4.3.76, update to version 4.3.77 or later.
