Summary

Moderate: linuxptp security, bug fix, and enhancement update

Details

The linuxptp packages provide Precision Time Protocol (PTP) implementation for Linux according to IEEE standard 1588 for Linux. The dual design goals are to provide a robust implementation of the standard and to use the most relevant and modern Application Programming Interfaces (API) offered by the Linux kernel.

The following packages have been upgraded to a later upstream version: linuxptp (3.1.1). (BZ#1895005)

Security Fix(es):

linuxptp: wrong length of one-step follow-up in transparent clock (CVE-2021-3571)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Additional Changes:

CVE-2021-3571 (GCVE-0-2021-3571)

Vulnerability from cvelistv5 – Published: 2021-07-09 10:33 – Updated: 2024-08-03 17:01

Summary

A flaw was found in the ptp4l program of the linuxptp package. When ptp4l is operating on a little-endian architecture as a PTP transparent clock, a remote attacker could send a crafted one-step sync message to cause an information leak or crash. The highest threat from this vulnerability is to data confidentiality and system availability. This flaw affects linuxptp versions before 3.1.1 and before 2.0.1.

Severity ?

No CVSS data available.
