EUVD-2026-32009

A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure...

JLSEC-2026-525

A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange,...

gnutls: gnutls: Memory corruption due to off-by-one error in PKCS#12 bag handling

A flaw was found in gnutls. An off-by-one error exists in the PKCS12 bag element bounds check. This vulnerability allows an remote attacker to write past the internal array of a PKCS12 bag when appending to a bag that already contains 32 elements. This memory corruption could lead to a denial of...

gnutls: gnutls: Information disclosure via heap overread in RSA key exchange

A flaw was found in libgnutls. A remote attacker, by sending an extremely short premaster secret during an RSA key exchange to a server using an RSA key backed by a PKCS11 token, could trigger a short heap overread. This memory corruption vulnerability could lead to information disclosure...

Batch Me If You Can: Coverage-Guided RPKI Fuzzing at Scale

The Resource Public Key Infrastructure RPKI has become essential to secure inter-domain routing. Despite its critical role, RPKI software remains largely untested beyond shallow parsing. Existing fuzzers, like AFL++ or libFuzzer, do not work well for RPKI as they assume a single, self-contained...

GnuTLS 安全漏洞

GnuTLS is an open-source, free security communication library developed by GnuTLS that enables the implementation of SSL, TLS, and DTLS protocols. GnuTLS has a security vulnerability, which stems from a single-bit error in the bounds checking of PKCS12 package elements. This vulnerability could...

Linux Distros Unpatched Vulnerability : CVE-2026-39831

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The Verify method for FIDO/U2F security key types [email protected], sk-ssh- [email protected] did not check the User Presence flag. Signatur...

PuTTY 资源管理错误漏洞

PuTTY is a suite of free Telnet, Rlogin and SSH client software from the individual developer Simon Tatham. The software is primarily used for remote administration of Linux systems. A resource management error vulnerability exists in PuTTY versions prior to 0.84, which stems from a double releas...

[SECURITY] Fedora 42 Update: nss-3.123.1-1.fc42

Network Security Services NSS is a set of libraries designed to support cross-platform development of security-enabled client and server applications. Applications built with NSS can support SSL v2 and v3, TLS, PKCS 5, PKCS 7, PKCS 11, PKCS 12, S/MIME, X.509 v3 certificates, and other security...

SUSE CVE-2026-39829

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public...

SUSE CVE-2026-39831

The Verify method for FIDO/U2F security key types [email protected], [email protected] did not check the User Presence flag. Signatures generated without physical touch were accepted, allowing unattended use of a hardware security key. To restore the previous behavior,...

SUSE CVE-2026-46595

Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any other type of callback is passed other than public key, then the source-address validation would be skipped...

AI-Driven Adaptive Adversaries and the Erosion of Cryptographic Trust in Public Key Systems

This paper examines the erosion of Public Key Cryptography PKC security under adaptive adversarial optimisation driven by artificial intelligence. The problem addressed is the growing mismatch between algorithm-centric cryptographic security models and operational attack realities, where...
