CVE-2026-69247

A flaw was found in cryptography, a Python package for cryptographic primitives. This vulnerability, known as a Bleichenbacher oracle, arises during PKCS7 EnvelopedData decryption. An attacker can exploit distinguishable error messages and timing differences during decryption to gain information...

CVE-2026-13586

A flaw was found in Bouncy Castle for Java. This vulnerability allows a remote attacker to cause a Denial of Service DoS by exploiting an iteration-count bound issue in the PKCS12 Message Authentication Code MAC and bag-decryption Key Derivation Function KDF. This could make the affected system...

Uncontrolled Resource Consumption

Bouncy Castle is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to insufficient bounds on PKCS12 MAC and bag-decryption KDF iteration counts, which allows an attacker to supply excessive iteration values and cause high computational resource consumption, resulting in...

openssl: PKCS#12 Files with PBMAC1 Are Accepted with Short HMAC Keys

A flaw was found in OpenSSL. This vulnerability allows a remote attacker to forge PKCS12 Public-Key Cryptography Standards 12 files that use Password-Based Message Authentication Code 1 PBMAC1 with short HMAC Hash-based Message Authentication Code keys. This can lead to a service accepting...

CVE-2026-15055

A flaw was found in Bouncy Castle for Java. An attacker could exploit this vulnerability by providing a specially crafted input to the PKCS8 / PBES2 decryptors. This input could specify an excessively high Key Derivation Function KDF cost, causing the decryptor to consume significant computationa...

openssl: Heap Use-After-Free in OpenSSL PKCS7_verify()

A flaw was found in OpenSSL. When processing a specially crafted PKCS7 or S/MIME Secure/Multipurpose Internet Mail Extensions signed message, a heap use-after-free vulnerability in the PKCS7verify function can be triggered. This occurs if the SignedData digestAlgorithms field is present as an emp...

librenswan: IKEv1 Denial of Service via RSA-SHA1 (PKCS#1 Version 1.5 Encrypted) authentication payload

A flaw was found in Libreswan's implementation of IKEv1 authentication via raw RSA signatures. When processing an IKEv1 packet using PKCS 1 v1.5 RSA encryption, the RSAauthenticatehashsignaturerawrsa function fails to properly validate the length of the authentication hash. A remote,...
