TITLE

Perl Integer overflow vulnerability in

DESCRIPTION

Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection. Perl Exists in an integer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be put into a state. An input validation error vulnerability exists in Perl versions prior to 5.30.3. The vulnerability is caused by the program's incorrect handling of the \"PL_regkind[OP(n)] == NOTHING\" case. Summary: Red Hat Advanced Cluster Management for Kubernetes 2.0.8 General Availability release, which fixes bugs and security issues. Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments.
