OpenSSL Releases Patch for 2 New High-Severity Vulnerabilities

The OpenSSL project has rolled out fixes to contain two high-severity flaws in its widely used cryptography library that could result in a denial-of-service DoS and remote code execution. The issues, tracked as CVE-2022-3602 and CVE-2022-3786, have been described as buffer overrun vulnerabilities...

CVE-2022-3786

Fedora 36 : openssl (2022-502f096dce)

The remote Fedora 36 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2022-502f096dce advisory. Security fix for CVE-2022-3602 and CVE-2022-3786 Tenable has extracted the preceding description block directly from the Fedora security advisory...

Oracle Linux 9 : openssl (ELSA-2022-9968)

The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-9968 advisory. - Add units tests for CVE-2022-3786, CVE-2022-3602 patches - Fix CVE-2022-3786, CVE-2022-3602 - CVE-2022-2097: AES OCB fails to encrypt some bytes on...

OpenSSL 3.0.0 < 3.0.7 Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 3.0.7. It is, therefore, affected by multiple vulnerabilities as referenced in the 3.0.7 advisory. - A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs...

CVE-2022-3786

OpenSSL CVE-2022-3602 and CVE-2022-3786 describe buffer overflows in X.509 name-constraint processing triggered by crafted email addresses in certificates, potentially crashing the TLS client/server and, in some scenarios, enabling remote code execution. Documents confirm the issues affect OpenSS...

CVE-2022-3786

A buffer overrun can be triggered in X.509 certificate verification, specifically in name constraint checking. Note that this occurs after certificate chain signature verification and requires either a CA to have signed a malicious certificate or for an application to continue certificate...

The vulnerability of the /goform/form2WizardStep4 component of the D-Link DIR-816 A2 router’s microprogramming system allows a hacker to execute arbitrary code.

The vulnerability of the /goform/form2WizardStep4 component of the D-Link DIR-816 A2 router’s microprogramming system is related to the execution of operations outside the buffer in memory. Exploiting this vulnerability allows a malicious actor to execute arbitrary code using the wizardstep4pskpw...

The vulnerability of the Tunnel Mode mode in the implementation of SSL VPN technology for FortiOS operating systems allows a perpetrator to cause a service failure.

The vulnerability of the Tunnel Mode mode in the FortiOS operating system-based SSL VPN technology stems from the fact that data operations go beyond the buffer in memory when processing LCP packets. Exploiting this vulnerability can allow a malicious actor to cause service interruptions remotely...
