Debian Security Advisory DSA-4938-1 security AT debian.org

Package : linuxptp
CVE ID : CVE-2021-3570
Debian Bug : 990748
Miroslav Lichvar reported that the ptp4l program in linuxptp, an
implementation of the Precision Time Protocol (PTP), does not validate
the messageLength field of incoming messages, allowing a remote attacker
to cause a denial of service, information leak, or potentially remote
code execution.
For the stable distribution (buster), this problem has been fixed in
version 1.9.2-1+deb10u1.
We recommend that you upgrade your linuxptp packages.
For the detailed security status of linuxptp please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/linuxptp
Further information about Debian Security Advisories, how to apply
these updates to your system and frequently asked questions can be
