Vulnerability from cvelistv5 – Published: 2017-10-29 06:00 – Updated: 2024-08-05 20:13

Summary

rsync 3.1.3-development before 2017-10-24 mishandles archaic checksums, which makes it easier for remote attackers to bypass intended access restrictions. NOTE: the rsync development branch has significant use beyond the rsync developers, e.g., the code has been copied for use in various GitHub projects.
