Security Advisory YSA-2021-03 | Yubico

A security update for pam-u2f resolves a logic issue that, depending on the pam-u2f configuration and the application used, could lead to a local PIN bypass. This issue does not allow user presence touch or cryptographic signature verification to be bypassed, so an attacker would still need to...

CVE-2021-21339

CVE-2021-21339 affects TYPO3, a PHP-based CMS. The issue is that user session identifiers were stored in cleartext in versions prior to 6.2.57, 7.6.51, 8.7.40, 9.5.25, 10.4.14, and 11.1.1. The root cause is storage of session identifiers without additional cryptographic hashing, and exploitation ...

CVE-2019-0223

A cryptographic weakness was discovered in qpid-proton's use of TLS. If the qpid-proton client was used without client certificates, it would accept an anonymous cipher offered by the server. A man-in-the-middle attacker could use this to silently intercept traffic that should have been encrypted...

DNSSEC: How It Works & Key Considerations

From its beginnings as a replacement for a centralized database, the Domain Name System DNS has evolved into a dynamic, highly distributed, question-answer protocol. The proverbial "phone book of the internet" has increased in complexity and scale alongside the rapid growth of the World Wide Web...

Tenable SecurityCenter 5.9.x to 5.12.x SimpleSAMLPHP Privilege Escalation (TNS-2020-01)

According to its self-reported version, the Tenable SecurityCenter application installed on the remote host is 5.9.x, 5.10.x, 5.11.x or 5.12.x. It is, therefore, affected by a privilege escalation vulnerability due to incorrect validation of cryptographic signatures in XML messages in the...
