Package        : ntpsec
CVE ID         : CVE-2023-4012
Debian Bug     : 1038422

It was discovered that ntpd in ntpsec, a secure, hardened, and improved
implementation derived from the original NTP project, could crash if NTS
is disabled and an NTS-enabled client request (mode 3) is received.

For the stable distribution (bookworm), this problem has been fixed in
version 1.2.2+dfsg1-1+deb12u1.

We recommend that you upgrade your ntpsec packages.

For the detailed security status of ntpsec please refer to its security
tracker page at:
