CVE-2021-28153: file-roller symlink attack (#2325) · Issues · GNOME / GLib

An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also creates the target of the symlink as an empty file, which could conceivably have security relevance if the symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents of that file correctly remain unchanged.)

CVE-2020-13558: TALOS-2020-1172 || Cisco Talos Intelligence Group

A code execution vulnerability exists in the AudioSourceProviderGStreamer functionality of Webkit WebKitGTK 2.30.1. A specially crafted web page can lead to a use after free.

CVE-2021-22877: Wrong (malformed) external storage credentials saved in `oc_storages_credentials` · Issue #24600 · nextcloud/server

A missing user check in Nextcloud prior to 20.0.6 inadvertently populates a user's own credentials for other users external storage configuration when not already configured yet.

CVE-2021-21274: Release v1.25.0 · matrix-org/synapse

Synapse is a Matrix reference homeserver written in python (pypi package matrix-synapse). Matrix is an ecosystem for open federated Instant Messaging and VoIP. In Synapse before version 1.25.0, a malicious homeserver could redirect requests to their .well-known file to a large file. This can lead to a denial of service attack where homeservers will consume significantly more resources when requesting the .well-known file of a malicious homeserver. This affects any server which accepts federation requests from untrusted servers. Issue is resolved in version 1.25.0. As a workaround the `federation_domain_whitelist` setting can be used to restrict the homeservers communicated with over federation.
