DEBIAN-CVE-2026-93575

A flaw was found in Netty's MqttDecoder. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted MQTT CONNECT packet. The decoder fails to properly validate the 'Properties Length' against the 'Remaining Length', allowing an attacker to bypass size limits...

DEBIAN-CVE-2026-93561

A flaw was found in io.netty/netty-codec-memcache. The Memcache binary protocol codec incorrectly reads keyLength and extrasLength as signed Java types instead of unsigned, as specified by the protocol. A malicious Memcache server can exploit this type mismatch by sending a specially crafted...

DEBIAN-CVE-2026-93563

A flaw was found in Netty's SmtpResponseDecoder component. A remote attacker, acting as a malicious or man-in-the-middle MITM SMTP server, could exploit this by sending a specially crafted, unbounded multi-line SMTP response without a terminator. This vulnerability leads to unbounded memory...

DEBIAN-CVE-2026-93572

A flaw was found in Netty's RedisArrayAggregator component. A remote attacker can exploit this vulnerability by sending specially crafted nested Redis RESP array headers. This can cause the RedisArrayAggregator to eagerly preallocate a large amount of heap memory, leading to heap memory exhaustio...
