Announcement ID: SUSE-SU-2014:1690-1

An update that fixes two vulnerabilities is now available.

Description:


The network timeservice ntp was updated to fix critical security issues
(bnc#910764, CERT VU#852879)

* A potential remote code execution problem was found inside ntpd. The
functions crypto_recv() (when using autokey authentication),
ctl_putdata(), and configure() where updated to avoid buffer overflows
that could be exploited. (CVE-2014-9295)
* Furthermore a problem inside the ntpd error handling was found that is
missing a return statement. This could also lead to a potentially attack
vector. (CVE-2014-9296)
