Traefik 安全漏洞

Traefik is an open-source reverse proxy and load balancing tool developed by Traefik. Versions of Traefik such as 2.11.40, 3.0.0-beta1 to 3.6.11, and 3.7.0-ea.1 contain security vulnerabilities. These vulnerabilities stem from issues with the TLS SNI pre-sniffing logic, which may allow for...

PT-2026-26679

libfuse is the reference implementation of the Linux FUSE. From version 3.18.0 to before version 3.18.2, a NULL pointer dereference and memory leak in fuse uring init queue allows a local user to crash the FUSE daemon or cause resource exhaustion. When numa alloc local fails during io uring queue...

Linux Distros Unpatched Vulnerability : CVE-2026-3549

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Heap Overflow in TLS 1.3 ECH parsing. An integer underflow existed in ECH extension parsing logic when calculating a buffer length, which resulted in writing...

Cryptomator 安全漏洞

Cryptomator is a simple digital self-defense tool from the Cryptomator community. Versions of Cryptomator prior to 1.19.1 contained security vulnerabilities. These vulnerabilities stemmed from the unlocking process based on Hub, which did not enforce the use of HTTPS. This could lead to network...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow due to an integer underflow in the ECH extension parsing logic when calculating a buffer length, leading to writing beyond the bounds of an allocated buffer. An attacker can cause memory corruption or...

Missing Cryptographic Step

Overview Affected versions of this package are vulnerable to Missing Cryptographic Step due to missing validation in the keyshare process during the TLS 1.3 HelloRetryRequest handshake. An attacker can compromise the confidentiality of encrypted communications by sending a crafted HelloRetryReque...

EUVD-2026-13209

Missing required cryptographic step in the TLS 1.3 client HelloRetryRequest handshake logic in wolfSSL could lead to a compromise in the confidentiality of TLS-protected communications via a crafted HelloRetryRequest followed by a ServerHello message that omits the required keyshare extension,...

DEBIAN-CVE-2026-3230

Missing required cryptographic step in the TLS 1.3 client HelloRetryRequest handshake logic in wolfSSL could lead to a compromise in the confidentiality of TLS-protected communications via a crafted HelloRetryRequest followed by a ServerHello message that omits the required keyshare extension,...

DEBIAN-CVE-2026-3549

Heap Overflow in TLS 1.3 ECH parsing. An integer underflow existed in ECH extension parsing logic when calculating a buffer length, which resulted in writing beyond the bounds of an allocated buffer. Note that in wolfSSL, ECH is off by default, and the ECH standard is still evolving...

CVE-2026-3230

Missing required cryptographic step in the TLS 1.3 client HelloRetryRequest handshake logic in wolfSSL could lead to a compromise in the confidentiality of TLS-protected communications via a crafted HelloRetryRequest followed by a ServerHello message that omits the required keyshare extension,...

UBUNTU-CVE-2026-4395

Heap-based buffer overflow in the KCAPI ECC code path of wceccimportx963ex in wolfSSL wolfcrypt allows a remote attacker to write attacker-controlled data past the bounds of the pubkeyraw buffer via a crafted oversized EC public key point. The WOLFSSLKCAPIECC code path copies the input to...

CVE-2026-3230 Improper key_share validation in TLS 1.3 HelloRetryRequest

Missing required cryptographic step in the TLS 1.3 client HelloRetryRequest handshake logic in wolfSSL could lead to a compromise in the confidentiality of TLS-protected communications via a crafted HelloRetryRequest followed by a ServerHello message that omits the required keyshare extension,...

CVE-2026-3230

wolfSSL’s TLS 1.3 client logic is affected by an improper key_share handling during HelloRetryRequest, allowing a crafted HelloRetryRequest followed by a ServerHello without the key_share extension to derive predictable traffic secrets from the (EC)DHE shared secret. Affected component: TLS hands...
