Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-06-24 15:33:53 UTC 
Description:
"MEDIUM: Sec 3661: Memory leak with CMAC keys

    Systems that use a CMAC algorithm in ntp.keys will not release a bit of memory on each packet that uses a CMAC key, eventually causing ntpd to run out of memory and fail. The CMAC cleanup from https://bugs.ntp.org/3447, part of ntp-4.2.8p11 and ntp-4.3.97, introduced a bug whereby the CMAC data structure was no longer completely removed.
    Reported by Martin Burnicki of Meinberg."
