Security Advisory Description
o CVE-2015-5194
The log_config_command function in ntp_parser.y in ntpd in NTP before
4.2.7p42 allows remote attackers to cause a denial of service (ntpd crash)
via crafted logconfig commands.
o CVE-2015-5195
ntp_openssl.m4 in ntpd in NTP before 4.2.7p112 allows remote attackers to
cause a denial of service (segmentation fault) via a crafted statistics or
filegen configuration command that is not enabled during compilation.
Impact
The ntpd process could stop responding, due to an uninitialized variable, when
processing malformed configuration commands.
F5 has evaluated this vulnerability as having low impact to the BIG-IP product
line for the following reasons:
o This issue is not exposed in a BIG-IP system default configuration.
o The configuration that exposes the issue is not recommended by F5.
Security Advisory Status
F5 Product Development has assigned IDs 568052 and 568054 (BIG-IP), ID 568165
(BIG-IQ), and ID 568170 (Enterprise Manager) to this vulnerability, and has
evaluated the currently supported releases for potential vulnerability.
