Detail

Synopsis

A vulnerability in libgdata could allow remote attackers to perform man-in-the-middle attacks.

Background

libgdata is a GLib-based library for accessing online service APIs using the GData protocol.

Description

An error in the "_gdata_service_build_session()" function of gdata-service.c prevents libgdata from properly validating certificates.

Impact

A remote attacker could perform man-in-the-middle attacks to spoof arbitrary SSL servers via a crafted certificate.

Workaround

There is no known workaround at this time.

Resolution

All libgdata users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/libgdata-0.8.1-r2"
