CVE-2020-6750: Fedoraproject Fedora

Medium severity, CVSS 5.9. EPSS: 2.2% chance of exploitation in the next 30 days.

GSocketClient in GNOME GLib through 2.62.4 may occasionally connect directly to a target address instead of connecting via a proxy server when configured to do so, because the proxy_addr field is mishandled. This bug is timing-dependent and may occur only sporadically depending on network delays. The greatest security relevance is in use cases where a proxy is used to help with privacy/anonymity, even though there is no technical barrier to a direct connection. NOTE: versions before 2.60 are unaffected.

Affected products

  • Fedoraproject Fedora: version 30 only; version 31 only
  • Gnome Glib: from 2.60.0, up to and including 2.62.4
