USN-2449-1 (UBUNTU-CVE-2014-9293)
Vulnerability from osv_ubuntu – Published: 2014-12-22 13:12 – Updated: 2026-02-10 04:40 – Source websiteNeel Mehta discovered that NTP generated weak authentication keys. A remote attacker could possibly use this issue to brute force the authentication key and send requests if permitted by IP restrictions. (CVE-2014-9293)
Stephen Roettger discovered that NTP generated weak MD5 keys. A remote attacker could possibly use this issue to brute force the MD5 key and spoof a client or server. (CVE-2014-9294)
Stephen Roettger discovered that NTP contained buffer overflows in the crypto_recv(), ctl_putdata() and configure() functions. In non-default configurations, a remote attacker could use these issues to cause NTP to crash, resulting in a denial of service, or possibly execute arbitrary code. The default compiler options for affected releases should reduce the vulnerability to a denial of service. In addition, attackers would be isolated by the NTP AppArmor profile. (CVE-2014-9295)
Stephen Roettger discovered that NTP incorrectly continued processing when handling certain errors. (CVE-2014-9296)
