MGASA-2020-0118 - Updated glib2.0 packages fix security vulnerability

Publication date: 06 Mar 2020
URL: https://advisories.mageia.org/MGASA-2020-0118.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2020-6750

The updated packages fix a security vulnerability:

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. (CVE-2020-6750)
