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...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered 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 speciall...

Medium: libtasn1

Issue Overview: When an input DER data contains a large number of SEQUENCE OF or SET OF elements, decoding the data and searching a specific element in it take quadratic time to complete. This could be utilized for a remote DoS attack by presenting a crafted certificate to the network peer...
