python-cryptography: python-cryptography: python-cryptography verifier accepts wildcard DNS names allowing escape from permittedSubtrees

A flaw was found in python-cryptography versions 46.0.6 through 48.x. The X.509 verifier incorrectly handles wildcard DNS Subject Alternative Names when evaluating permitted name constraints: a leaf SAN such as .example.com may be accepted under a more specific permitted subtree for example...

python-cryptography: python-cryptography: PKCS#7 EnvelopedData decryption exposes a Bleichenbacher oracle through distinguishable errors and timing

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...

python-cryptography: python-cryptography: Duplicate self-signed intermediates can cause exponential path-building

A flaw was found in python-cryptography. When processing invalid certificate chains that include duplicate self-signed certificates, the system recursively invokes the same certificate, leading to an exponential increase in processing time. A remote attacker could exploit this by providing a...
