Name of the Vulnerable Software and Affected Versions GLib versions 2.60 through 2.62.4

Description The issue concerns a timing-dependent bug where GSocketClient in GLib may occasionally connect directly to a target address instead of using a proxy server as configured. This occurs due to the mishandling of the proxy addr field and is influenced by network delays. The security impact is most significant in scenarios where a proxy is utilized for privacy or anonymity purposes.

Recommendations For versions 2.60 through 2.62.4, update to a version later than 2.62.4 to resolve the issue.
