Alpine: multiple synapse packages: security update to 1.85.1-r0

medium Tenable Cloud Security Plugin ID 426533

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - Synapse is a Matrix protocol homeserver written in Python with the Twisted framework. In affected versions
 it may be possible for a deactivated user to login when using uncommon configurations. This only applies
 if any of the following are true: 1. JSON Web Tokens are enabled for login via the `jwt_config.enabled`
 configuration setting. 2. The local password database is enabled via the `password_config.enabled` and
 `password_config.localdb_enabled` configuration settings *and* a user's password is updated via an admin
 API after a user is deactivated. Note that the local password database is enabled by default, but it is
 uncommon to set a user's password after they've been deactivated. Installations that are configured to
 only allow login via Single Sign-On (SSO) via CAS, SAML or OpenID Connect (OIDC); or via an external
 password provider (e.g. LDAP) are not affected. If not using JSON Web Tokens, ensure that deactivated
 users do not have a password set. This issue has been addressed in version 1.85.0. Users are advised to
 upgrade. (CVE-2023-32682)

 - Synapse is a Matrix protocol homeserver written in Python with the Twisted framework. A discovered oEmbed
 or image URL can bypass the `url_preview_url_blacklist` setting potentially allowing server side request
 forgery or bypassing network policies. Impact is limited to IP addresses allowed by the
 `url_preview_ip_range_blacklist` setting (by default this only allows public IPs) and by the limited
 information returned to the client: 1. For discovered oEmbed URLs, any non-JSON response or a JSON
 response which includes non-oEmbed information is discarded. 2. For discovered image URLs, any non-image
 response is discarded. Systems which have URL preview disabled (via the `url_preview_enabled` setting) or
 have not configured a `url_preview_url_blacklist` are not affected. This issue has been addressed in
 version 1.85.0. Users are advised to upgrade. User unable to upgrade may also disable URL previews.
