FreeBSD : Prosody XMPP server advisory 2026-04-29 (a420f545-442c-11f1-b9b5-589cfc0dc9a2)

high Nessus Plugin ID 311799

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 a vulnerability as referenced in the a420f545-442c-11f1-b9b5-589cfc0dc9a2 advisory.

 The Prosody team reports:
 Traffic patterns were discovered which can cause Prosody to consume excessive amounts of memory with much smaller amounts of incoming traffic. This traffic can be sent by unauthenticated connections. It was discovered that mod_proxy65s access control was broken and incomplete due to two bugs.
 The issue with unpausing connections was discovered and disclosed by Max Hearnden.

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

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

Solution

Update the affected packages.
