gajim - several

Several vulnerabilities have been discovered in Gajim, a feature-rich
Jabber client. The Common Vulnerabilities and Exposures project
identifies the following problems:

• CVE-2012-1987

  URL in an instant message.
• CVE-2012-2093
  Gajim is using predictable temporary files in an insecure manner when

  which results in the possibility to conduct SQL injection attacks.
