high Nessus Plugin ID 146835

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 32 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2021-54d3af6388 advisory.

- Prosody 0.11.8 ============== This is a new minor release for the 0.11.x stable branch, it includes bug fixes and performance improvements! Upstream would like to thank the Jitsi folks for helping to improve websocket performance in this and the previous release. This release also fixes a security issue, where channel binding, which connects the authentication layer (i.e. SASL) with the security layer (i.e. TLS) to detect man-in-the-middle attacks, could be used on connections encrypted with TLS 1.3, despite the holy texts declaring this undefined. Security -------- * mod_saslauth: Disable tls-unique channel binding with TLS 1.3 (#1542) Fixes and improvements ---------------------- * net.websocket.frames:
Improve websocket masking performance by using the new util.strbitop * util.strbitop: Library for efficient bitwise operations on strings Minor changes ------------- * MUC: Correctly advertise whether the subject can be changed (#1155) * MUC: Preserve disco node attribute (or lack thereof) in responses (#1595) * MUC: Fix logic bug causing unnecessary presence to be sent (#1615) * mod_bosh: Fix error if client tries to connect to component (#425) * mod_bosh: Pick out the wait before checking it instead of earlier * mod_pep: Advertise base PubSub feature (#1632) * mod_pubsub: Fix notification stanza type setting (#1605) * mod_s2s: Prevent keepalives before client has established a stream * net.adns: Fix bug that sent empty DNS packets (#1619) * net.http.server: Dont send Content-Length on 1xx/204 responses (#1596) * net.websocket.frames: Fix length calculation bug (#1598) * util.dbuffer:
Make length API in line with Lua strings * util.dbuffer: Optimize substring operations * util.debug:
