Scientific Linux Security Update : ntp on SL4.x, SL5.x i386/x86_64
Medium Nessus Plugin ID 60526
SynopsisThe remote Scientific Linux host is missing a security update.
DescriptionA flaw was discovered in the way the ntpd daemon checked the return value of the OpenSSL EVP_VerifyFinal function. On systems using NTPv4 authentication, this could lead to an incorrect verification of cryptographic signatures, allowing time-spoofing attacks.
Note: This issue only affects systems that have enabled NTP authentication. By default, NTP authentication is not enabled.
After installing the update, the ntpd daemon will restart automatically.
SolutionUpdate the affected ntp package.
