Name of the Vulnerable Software and Affected Versions glib-networking (affected versions not specified)

Description A flaw exists where a remote attacker can cause a denial of service for an affected process or worker. This occurs when an application uses glib-networking with the GnuTLS backend enabled and performs certificate verification. By presenting a specially crafted certificate chain containing circular issuer relationships, an attacker can trigger an infinite loop during the verification process. This unbounded traversal consumes excessive CPU resources.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
