Summary

The GSocketClient component of GNOME GLib, up to version 2.62.4, has a vulnerability that may allow it to bypass the specified proxy settings, connecting directly to a target address unexpectedly. This issue arises from improper management of the proxy_addr field and is contingent on timing and network delays, making it sporadic in nature. This poses a significant risk in scenarios where proxies are employed for privacy and anonymity, as direct connections could expose user activities or data.
