MGASA-2020-0314 - Updated glib-networking packages fix security vulnerability

Publication date: 16 Aug 2020
URL: https://advisories.mageia.org/MGASA-2020-0314.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2020-13645

The updated packages fix a security vulnerability:

In GNOME glib-networking through 2.64.2, the implementation of
GTlsClientConnection skips hostname verification of the server's
TLS certificate if the application fails to specify the expected
server identity. This is in contrast to its intended documented
behavior, to fail the certificate verification. Applications that
fail to provide the server identity, including Balsa before 2.5.11
and 2.6.x before 2.6.1, accept a TLS certificate if the certificate
is valid for any host. (CVE-2020-13645)
