Description

Two security vulnerabilities have been identified in python-kdcproxy, a component related to Python in Red Hat Enterprise Linux 10.0 Extended Update Support. The first vulnerability (CVE-2025-59088) allows unauthenticated Server-Side Request Forgery (SSRF) via realm-controlled DNS SRV records. The second (CVE-2025-59089) enables a remote denial of service (DoS) through unbounded TCP upstream buffering. Red Hat has released an important security update addressing these issues for multiple architectures of Red Hat Enterprise Linux 10.0. Users are advised to apply the update as detailed in the Red Hat advisory.
