Description
Two security vulnerabilities were identified in python-kdcproxy, a Python module used in Red Hat Enterprise Linux 9.6 Extended Update Support. The first vulnerability (CVE-2025-59088) is an unauthenticated Server-Side Request Forgery (SSRF) via realm-controlled DNS SRV records. The second (CVE-2025-59089) is a remote denial-of-service (DoS) caused by unbounded TCP upstream buffering. Red Hat has issued an important security update addressing these issues for multiple architectures and variants of RHEL 9.6.
