Mandriva Linux Security Advisory MDVSA-2012:111

_______________________________________________________________________
Package : libgdata
Date : July 25, 2012
Affected: 2011.
_______________________________________________________________________
Problem Description:
A vulnerability has been discovered and corrected in libgdata:
It was found that previously libgdata, a GLib-based library for
accessing online service APIs using the GData protocol, did not
perform SSL certificates validation even for secured connections. An
application, linked against the libgdata library and holding the
trust about the other side of the connection being the valid owner
of the certificate, could be tricked into accepting of a spoofed SSL
certificate by mistake (MITM attack) (CVE-2012-1177).
The updated packages have been patched to correct this issue.
