Description Michael Harrison 2012-03-15 00:18:08 UTC
When accessing google services over SSL, the certificate is not validated, which allows a MITM attack that can expose user name and password. This bug can be easily exploited using a tool such as sslsniff.

Thanks for reporting, fixed in 0.8.1-r2 and 0.10.2.

Note that libgdata-0.8.1-r2 should be stabilized, but *not* libgdata-0.10.2 for now (the 0.10.x series has API changes that break evolution-data-server-2.x).

CVE-2012-1177 (
  libgdata before 0.10.2 and 0.11.x before 0.11.1 does not validate SSL
  certificates, which allows remote attackers to obtain user names and
  passwords via a man-in-the-middle (MITM) attack with a spoofed certificate.
