The vulnerability of OpenSSL’s parsing code for PKCS#12 file formats allows a hacker to induce a service failure.
The vulnerability of the PKCS12 format form field parsing code in the OpenSSL library is related to insufficient checking of unusual or exceptional states. Exploiting this vulnerability can allow an attacker to cause service failures...
RLSA-2026:1472 Important: openssl security update
OpenSSL is a toolkit that implements the Secure Sockets Layer SSL and Transport Layer Security TLS protocols, as well as a full-strength general-purpose cryptography library. Security Fixes: openssl: OpenSSL: Arbitrary code execution or denial of service through crafted PKCS12 file CVE-2025-11187...
CVE-2025-55292
Meshtastic is an open source mesh networking solution. In the current Meshtastic architecture, a Node is identified by their NodeID, generated from the MAC address, rather than their public key. This aspect downgrades the security, specifically by abusing the HAM mode which doesn't use encryption...
RHEL 10 : openssl (RHSA-2026:1496)
The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:1496 advisory. OpenSSL is a toolkit that implements the Secure Sockets Layer SSL and Transport Layer Security TLS protocols, as well as a full-strength...
CVE-2026-24882
In GnuPG before 2.5.17, a stack-based buffer overflow exists in tpm2daemon during handling of the PKDECRYPT command for TPM-backed RSA and ECC keys...
AZL-76155 CVE-2026-22795 affecting package hvloader for versions less than 1.0.1-18
Issue summary: An invalid or NULL pointer dereference can happen in an application processing a malformed PKCS12 file. Impact summary: An application processing a malformed PKCS12 file can be caused to dereference an invalid or NULL pointer on memory read, resulting in a Denial of Service. A type...
AZL-76152 CVE-2025-69419 affecting package hvloader for versions less than 1.0.1-18
Issue summary: Calling PKCS12getfriendlyname function on a maliciously crafted PKCS12 file with a BMPString UTF-16BE friendly name containing non-ASCII BMP code point can trigger a one byte write before the allocated buffer. Impact summary: The out-of-bounds write can cause a memory corruption...
CVE-2026-22796
Issue summary: A type confusion vulnerability exists in the signature verification of signed PKCS7 data where an ASN1TYPE union member is accessed without first validating the type, causing an invalid or NULL pointer dereference when processing malformed PKCS7 data. Impact summary: An application...
CVE-2025-11187
OpenSSL CVE-2025-11187 affects OpenSSL 3.6, 3.5 and 3.4 where PBMAC1 parameters in PKCS#12 MAC verification are not validated. The PBKDF2 salt and keylength are used without validation; if keylength exceeds the 64-byte derived key buffer, an attacker-controlled buffer overflow can occur, potentia...

OpenSSL 1.0.2 < 1.0.2zn Multiple Vulnerabilities
The version of OpenSSL installed on the remote host is prior to 1.0.2zn. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.2zn advisory. - Issue summary: A type confusion vulnerability exists in the signature verification of signed PKCS7 data where an ASN1TYPE union...
EUVD-2025-206344
A flaw was found in the GnuTLS library, specifically in the gnutlspkcs11tokeninit function that handles PKCS11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the applicatio...
CVE-2026-22791
openCryptoki is a PKCS11 library and tools for Linux and AIX. In 3.25.0 and 3.26.0, there is a heap buffer overflow vulnerability in the CKMECDHAESKEYWRAP implementation allows an attacker with local access to cause out-of-bounds writes in the host process by supplying a compressed EC public key...
RustCrypto: Elliptic Curves 输入验证错误漏洞
RustCrypto: Elliptic Curves is a Rust cryptographic library open-sourced by Rust Crypto. An input validation error vulnerability exists in RustCrypto: Elliptic Curves version 0.14.0-pre.0 and 0.14.0-rc.0, which stems from an unchecked slice-and-dice operation performed on an input buffer...
Meshtastic 安全漏洞
Meshtastic is a decentralized wireless off-grid mesh network LoRa protocol open-sourced by Meshtastic. A security vulnerability exists in Meshtastic versions 2.5 up to and including 2.7.15, which stems from a degradation attack path in the absence of PKI cryptographic flags, and could lead to an...
When RSA Fails: Exploiting Prime Selection Vulnerabilities in Public Key Cryptography
This paper explores vulnerabilities in RSA cryptosystems that arise from improper prime number selection during key generation. We examine two primary attack vectors: Fermat's factorization method, which exploits RSA keys generated with primes that are too close together, and the Greatest Common...
