Description

Two security vulnerabilities have been identified in the python-kdcproxy component of Red Hat Enterprise Linux 9.4 Extended Update Support. The first is an unauthenticated Server-Side Request Forgery (SSRF) vulnerability via realm-controlled DNS SRV records (CVE-2025-59088). The second is a remote denial-of-service (DoS) vulnerability caused by unbounded TCP upstream buffering (CVE-2025-59089). Red Hat has released an important security update addressing these issues for multiple architectures and variants of RHEL 9.4.
