GHSA-6XVM-J4WR-6V98 Quinn affected by unauthenticated remote DoS via panic in QUIC transport parameter parsing

Summary A remote, unauthenticated attacker can trigger a denial of service in applications using vulnerable quinn versions by sending a crafted QUIC Initial packet containing malformed quictransportparameters. In quinn-proto parsing logic, attacker-controlled varints are decoded with unwrap, so...

CVE-2026-31812 Quinn affected by unauthenticated remote DoS via panic in QUIC transport parameter parsing

Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol. Prior to 0.11.14, a remote, unauthenticated attacker can trigger a denial of service in applications using vulnerable quinn versions by sending a crafted QUIC Initial packet containing malformed...

CVE-2026-31812

In Quinn (Rust, QUIC), the quinn-proto parsing path decodes attacker-controlled varints with unwrap(), so a crafted QUIC Initial packet containing malformed quic_transport_parameters can trigger an unexpected end and panic. This remote, unauthenticated DoS is reachable over the network and affect...

BIT-GOLANG-2026-27138 Panic in name constraint checking for malformed certificates in crypto/x509

Certificate verification can panic when a certificate in the chain has an empty DNS name and another certificate in the chain has excluded name constraints. This can crash programs that are either directly verifying X.509 certificate chains, or those that use TLS...

EulerOS 2.0 SP13 : golang (EulerOS-SA-2026-1240)

According to the versions of the golang packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : The Reader.ReadResponse function constructs a response string through repeated string concatenation of lines. When the number of lines in a respon...

EUVD-2026-10334

The rtsockmsgbuffer function serializes routing information into a buffer. As a part of this, it copies sockaddr structures into a sockaddrstorage structure on the stack. It assumes that the source sockaddr length field had already been validated, but this is not necessarily the case, and it's...

RUSTSEC-2026-0037 Denial of service in Quinn endpoints

Receiving QUIC transport parameters containing invalid values could lead to a panic. Unfortunately the maintainers did not properly assess usage of unwrap calls in the transport parameters parsing code, and we did not have sufficient fuzzing coverage to find this issue. We have since added a...

CVE-2026-29781

Sliver is a command and control framework that uses a custom Wireguard netstack. In versions from 1.7.3 and prior, a vulnerability exists in the Sliver C2 server's Protobuf unmarshalling logic due to a systemic lack of nil-pointer validation. By extracting valid implant credentials and omitting...
