SCA: security update for github.com/matrix-org/dendrite, github.com/matrix-org/gomatrixserverlib (GHSA-grvv-h2f9-7v9c)
high Tenable Self-Hosted Container Security Plugin ID 415290
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- gomatrixserverlib is a Go library for matrix protocol federation. Dendrite is a Matrix homeserver written
in Go, an alternative to Synapse. The power level parsing within gomatrixserverlib was failing to parse
the `"events_default"` key of the `m.room.power_levels` event, defaulting the event default power level to
zero in all cases. Power levels are the matrix terminology for user access level. In rooms where the
`"events_default"` power level had been changed, this could result in events either being incorrectly
authorised or rejected by Dendrite servers. gomatrixserverlib contains a fix as of commit `723fd49` and
Dendrite 0.9.3 has been updated accordingly. Matrix rooms where the `"events_default"` power level has not
been changed from the default of zero are not vulnerable. Users are advised to upgrade. There are no known
workarounds for this issue. (CVE-2022-36009)
