Severity: normal
Exploitable: remote
Date: August 14, 2012
Bug(s): #408245
ID: 201208-06

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.


Affected Packages

Package: dev-libs/libgdata
Vulnerable: < 0.8.1-r2
Unaffected: >= 0.8.1-r2
Architectures: All supported architectures


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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/libgdata-0.8.1-r2"
