Important: openssl

Issue Overview: The BNmodsqrt function, which computes a modular square root, contains a bug that can cause it to loop forever for non-prime moduli. Internally this function is used when parsing certificates that contain elliptic curve public keys in compressed form or explicit elliptic curve...

Vulnerability fixed in OpenSSL

A vulnerability has been fixed in OpenSSL. The vulnerability allows an unauthenticated malicious person to cause a denial-of-service. To do so, the malicious party must offer a specially crafted certificate to the system that of OpenSSL. The vulnerability is caused by the "BNmodsqrt" function. Th...

CVE-2022-0778

A flaw was found in OpenSSL. It is possible to trigger an infinite loop by crafting a certificate that has invalid elliptic curve parameters. Since certificate parsing happens before verification of the certificate signature, any process that parses an externally supplied certificate may be subje...

Stolen Nvidia certificates used to sign malware—here’s what to do

As we wrote on March 3, 2022 Nvidia, was recently attacked by the LAPSUS$ ransomware group. The ensuing data leak included two of NVIDIA’s code signing certificates. Those certificates are now being used to sign malware. Leaked signing certificates from major vendors like Nvidia come with huge...

A flaw was found in Cockpit in versions prior to 260 in the way it handles the certificate verification performed by the System Security Services Daemon (SSSD). This flaw allows client certificates to authenticate successfully regardless of the Certificate Revocation List (CRL) configuration or the certificate status. The highest threat from this vulnerability is to confidentiality.
