Siemens SIMATIC S7-1500 and Ruggedcom ROX Devices Inefficient Algorithmic Complexity (CVE-2024-12243)

A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially...

python-cryptography: NULL-dereference when loading PKCS7 certificates

A null-pointer dereference vulnerability was found in python-cryptography during the loading of PKCS7 certificates. Invoking "loadpempkcs7certificates" or "loadderpkcs7certificates" can trigger this issue and lead to subsequent segmentation fault and result in a Denial of Service DoS for any...
