Security update for ntp
SUSE Security Update: Security update for ntp
These security issues were fixed:
- CVE-2014-9294: util/ntp-keygen.c in ntp-keygen used a weak RNG seed,
which made it easier for remote attackers to defeat cryptographic
protection mechanisms via a brute-force attack (bnc#910764 911792).
- CVE-2014-9293: The config_auth function in ntpd, when an auth key was
not configured, improperly generated a key, which made it easier for
remote attackers to defeat cryptographic protection mechanisms via a
brute-force attack (bnc#910764 911792).
- CVE-2014-9298: ::1 can be spoofed on some OSes, so ACLs based on IPv6
::1 addresses could be bypassed (bnc#911792).
- CVE-2014-9297: Information leak by not properly checking a length in
several places in ntp_crypto.c (bnc#911792).
