BIT-GOLANG-2026-32283 Unauthenticated TLS 1.3 KeyUpdate record can cause persistent connection retention and DoS in crypto/tls

If one side of the TLS connection sends multiple key update messages post-handshake in a single record, the connection can deadlock, causing uncontrolled consumption of resources. This can lead to a denial of service. This only affects TLS 1.3...

KeePassXC is an open-source cross-platform password manager. KeePassXC has code vulnerabilities, which stem from uncontrolled OpenSSL configuration paths, potentially leading to local privilege escalation...

Security Bulletin: Vulnerabilities in urllib3, router, qs, cryptography, axios might affect IBM Storage Defender Sentinel Anomaly Scan Engine.

Summary IBM Storage Defender Sentinel Anomaly Scan Engine can be affected by vulnerabilities in urllib3, router, qs, cryptography, and axios. Vulnerabilities include allowing an attacker to cause cross-site scripting, input improper data, provide a public key point from a small order subgroup, an...

CVE-2026-5295

A stack buffer overflow exists in wolfSSL's PKCS7 implementation in the wcPKCS7DecryptOri function in wolfcrypt/src/pkcs7.c. When processing a CMS EnvelopedData message containing an OtherRecipientInfo ORI recipient, the function copies an ASN.1-parsed OID into a fixed 32-byte stack buffer...

CVE-2026-39892

A flaw was found in the cryptography library. This vulnerability occurs when a non-contiguous buffer is passed to certain application programming interfaces APIs that accept Python buffers, such as Hash.update. A remote attacker could exploit this to cause a buffer overflow, potentially leading t...

crypto/tls: golang: Go crypto/tls: Denial of Service via multiple TLS 1.3 key update messages

A flaw was found in the crypto/tls package within the Go golang standard library, specifically affecting TLS 1.3 connections. A remote attacker can exploit this vulnerability by sending multiple key update messages in a single record after the handshake. This can cause the connection to deadlock,...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in the update function when non-contiguous buffers are provided as input. An attacker can cause memory corruption or unintended behavior by supplying specially crafted non-contiguous buffers to APIs that accept Pytho...

GHSA-P423-J2CM-9VMQ Cryptography vulnerable to buffer overflow if non-contiguous buffers were passed to APIs

If a non-contiguous buffer was passed to APIs which accepted Python buffers e.g. Hash.update, this could lead to buffer overflows. For example: python h = HashSHA256 b.updatebuf::-1 would read past the end of the buffer on Python 3.11...

DEBIAN-CVE-2026-32280

During chain building, the amount of work that is done is not correctly limited when a large number of intermediate certificates are passed in VerifyOptions.Intermediates, which can lead to a denial of service. This affects both direct users of crypto/x509 and users of crypto/tls...

CVE-2026-32280 Unexpected work during chain building in crypto/x509

During chain building, the amount of work that is done is not correctly limited when a large number of intermediate certificates are passed in VerifyOptions.Intermediates, which can lead to a denial of service. This affects both direct users of crypto/x509 and users of crypto/tls...

cryptography 安全漏洞

cryptography is a Python cryptographic authority open-source library. Versions of cryptography from 45.0.0 to 46.0.7 had security vulnerabilities; these vulnerabilities stemmed from improper buffer handling, which could lead to buffer overflows...

CVE-2026-32877

A flaw was found in Botan, a C++ cryptography library. During SM2 decryption, the library failed to validate the length of the authentication code value C3 before comparison. A remote attacker could exploit this by providing a specially crafted invalid ciphertext, leading to a heap over-read of u...

An issue was discovered in Mbed TLS before 3.6.6 and 4.x before 4.1.0 and TF-PSA-Crypto before 1.1.0. There is a Predictable Seed in a Pseudo-Random Number Generator PRNG...

CVE-2026-34871

CVE-2026-34871 affects Mbed TLS before 3.6.6 and 4.x before 4.1.0, due to a Predictable Seed in the PRNG. Evidence from multiple advisories notes remediation by upgrading to 3.6.6 (or newer) where getrandom is unavailable and /dev/urandom is used as fallback. Impact on confidentiality and integri...
