ssh3

!NOTE SSH3 可能会更改名称。它仍然是运行在 HTTP/3 扩展连接之上的 SSH 连接协议 RFC4254，但所需的更改非常重大，且与流行 SSH 实现的设计理念相距甚远，因此难以考虑集成。规范草案已经重命名为 "Remote Terminals over HTTP/3"，但我们需要一些时间来想出一个好听的永久名称。 SSH3: 使用 HTTP/3 实现更快、更丰富的安全 Shell SSH3 是对 SSH 协议的彻底重新审视，将其语义映射到 HTTP 机制之上。它源自我们的研究工作，我们（研究人员）最近将其作为 Internet-Draft...

RockyLinux 10 : openssl (RLSA-2026:67154)

The remote RockyLinux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:67154 advisory. openssl: OpenSSL: Denial of Service via unbounded memory growth in QUIC server CVE-2026-14456 openssl: QUIC server may trigger double free when...

openssl: QUIC ACK-only packet retention can cause memory exhaustion

A flaw was found in OpenSSL. The QUIC protocol implementation retains metadata for ACK-only packets for the lifetime of a connection, leading to excessive memory consumption. This allows a peer to repeatedly send ack-eliciting packets while not acknowledging ACK-only responses to cause memory...

CVE-2026-78662

Previously, a channel registered in the mux's chanList is not usable until it is established. A malicious peer was able flood the channel's incomingRequests, deadlocking the entire connection. Now, we add an atomic established state, set when a channel becomes usable. Until such a time,...

USN-8678-3: OpenSSL vulnerability

USN-8673-1 fixed vulnerabilities in OpenSSL. The update inadvertently left out the fix for CVE-2026-75803 in Ubuntu 26.04 LTS. This update fixes the problem. We apologize for the inconvenience. Original advisory details: It was discovered that OpenSSL incorrectly handled the QUIC server incoming...

CVE-2026-78966

A flaw was found in Google Chrome. An externally controlled reference within the QUIC protocol could allow a remote attacker to bypass the web origin policy. This vulnerability can be exploited by enticing a user to visit a specially crafted HTML page. The bypass of the web origin policy could le...

CVE-2026-63075

Issue summary: When OpenSSL processes QUIC traffic from a peer that repeatedly sends ack-eliciting packets while not acknowledging ACK-only responses, the QUIC stack can retain ACK-only packet metadata for the lifetime of the connection. Impact summary: A remote peer that can complete a QUIC...

Astra Linux – Vulnerability in Chromium

The use of “after free” in QUIC in Google Chrome before version 124.0.6367.60 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption through a crafted HTML page. Chromium security severity: Medium...

Astra Linux – Vulnerability in Firefox

Data was not properly sanitized during the decoding of a QUIC ACK frame; this could have led to unrestricted memory consumption and a crash. This vulnerability affects Firefox versions earlier than 124...

CVE-2026-25800

A flaw was found in Quinn, a Rust implementation of the QUIC transport protocol. A remote attacker can exploit this vulnerability by sending specially crafted QUIC stream fragments with many gaps. This can lead to high buffer overhead in the Assembler component, causing memory exhaustion and a...
