DescriptionA security vulnerability has been identified in all supported OpenSSL versions related to verifying X.509 certificate chains that include policy constraints. This flaw allows attackers to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use of computational resources, leading to a denial of service (DoS) attack on affected systems. Policy processing is disabled by default but can be enabled by passing the -policy' argument to the command line utilities or calling the X509_VERIFY_PARAM_set1_policies()' function.A security vulnerability has been identified in all supported OpenSSL versions related to verifying X.509 certificate chains that include policy constraints.

Unless explicitly stated as not affected, all previous versions of packages in any minor update stream of a product listed here should be assumed vulnerable, although may not have been subject to full analysis.
