GDBusServer: glib2: GDBusServer pre-authentication DoS via unbounded SASL line buffering

A denial-of-service and resource exhaustion vulnerability exists within the GDBus component of GLib. The gdbusauth authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input...

glib: path traversal in glib/gio/gdbusauthmechanismsha1.c via keyring_lookup_entry and mechanism_client_data_receive

A flaw was found in GLib. The D-Bus client-side implementation of the DBUSCOOKIESHA1 SASL authentication mechanism does not validate the cookiecontext parameter received from the server. A malicious D-Bus server can supply a cookiecontext containing path traversal sequences, causing the client to...

CVE-2026-75853 ArcadeDB Gremlin Wire Protocol Authorization Bypass Cross-Database

ArcadeDB's Gremlin wire-protocol plugin com.arcadedb:arcadedb-gremlin in versions = 26.7.3 enforces authentication SASL PLAIN but performs no authorization: it never checks database access permissions canAccessToDatabase and never binds the authenticated principal into the engine. As a result, an...

PCP: PCP: Denial of Service due to signed integer overflow

A signed integer overflow in the PCP pmGetPDU function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service DoS for subsequent packet reads...
