Upstream source description

A flaw was found in glib-networking. A remote attacker can exploit this vulnerability by presenting a specially crafted certificate chain to an application that uses glib-networking with the GnuTLS backend enabled and performs certificate verification. This crafted chain, which contains circular issuer relationships, can cause an infinite loop during certificate verification. The unbounded traversal consumes excessive CPU resources, leading to a denial of service for the affected process or worker.
