Debian Security Advisory DSA-4938-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
July 13, 2021 https://www.debian.org/security/faq
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
