Name of the Vulnerable Software and Affected Versions OpenSSL (affected versions not specified)
Description A security issue has been identified in OpenSSL related to the verification of X.509 certificate chains that include policy constraints. Attackers may be able to exploit this issue 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 by calling the X509 VERIFY PARAM set1 policies() function.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
