FreeBSD : net/rsync -- multiple vulnerabilities (fee67ad5-a05e-11f1-ad2b-40b034429ecf)

critical Nessus Plugin ID 341069

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the fee67ad5-a05e-11f1-ad2b-40b034429ecf advisory.

rsync project reports:
This release fixes 33 security issues found during a focused audit of rsync's path handling and daemon protocol, a companion daemon-protocol fuzzing pass, and reports from external researchers -- plus several robustness hardenings. CVE IDs were assigned by VulnCheck (CNA); the precise introduced in version ranges accompany each advisory, and many are much narrower than everything before 3.5.0. Every fix ships with a regression test in the test suite that fails on the unfixed tree.
support/rrsync (the restricted SSH wrapper):
Daemon protocol / identity:
Injection and memory safety:
Peer-triggerable memory corruption in the daemon protocol:
Daemon availability and access control:
Client-side:

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
