This pkg has no registered maintainer, so assigning globally; CC'ing some packagers who have done recent commits of it.

Comment 2 David Walser 2020-02-25 14:46:55 CET
Fedora advisory for 2.60.x (which we have in Mageia 7) from February 23:
https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/thread/KJMLGW55HOQXHMTIPH2PWXFRBNBWVO4W/

This was fixed in 2.62.5 and 2.63.6 (now in Cauldron).

Whiteboard: MGA7TOO => (none)
Source RPM: glib2.0-2.63.5-2.mga8.src.rpm => glib2.0-2.60.2-1.mga7.src.rpm
Version: Cauldron => 7

Comment 3 Nicolas Salguero 2020-02-25 15:23:26 CET
Suggested advisory:
========================

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)

Comment 4 Herman Viaene 2020-02-28 15:13:49 CET
MGA7-64 Plasma on Lenovo B50
No installation issues.
Ref. to bug 25276 for tests. This bug mentions to reboot after installation, so I did it as well, but MCC does not ask for it.
Anyway, after reboot found no problems. played mpeg and odp files over NFS accessed shares over wifi.
Installed also anki as in bug 25276, opens OK.

Comment 5 Thomas Andrews 2020-03-01 14:41:48 CET
The tester in Bug 25276 updated some glibc packages along with the glib2.0 packages. Glibc generated the need for the reboot.

Validating. Advisory in Comment 3.
