Ubuntu Security Notice USN-781-1              June 03, 2009
pidgin vulnerabilities
CVE-2009-1373, CVE-2009-1374, CVE-2009-1375, CVE-2009-1376
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 8.04 LTS
Ubuntu 8.10
Ubuntu 9.04

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 8.04 LTS:
  pidgin                          1:2.4.1-1ubuntu2.4

Ubuntu 8.10:
  pidgin                          1:2.5.2-0ubuntu1.2

Ubuntu 9.04:
  pidgin                          1:2.5.5-1ubuntu8.1

After a standard system upgrade you need to restart Pidgin to effect
the necessary changes.

Details follow:

It was discovered that Pidgin did not properly handle certain malformed
messages when sending a file using the XMPP protocol handler. If a user
were tricked into sending a file, a remote attacker could send a specially
crafted response and cause Pidgin to crash, or possibly execute arbitrary
code with user privileges. (CVE-2009-1373)

It was discovered that Pidgin did not properly handle certain malformed
messages in the QQ protocol handler. A remote attacker could send a
specially crafted message and cause Pidgin to crash. This issue only
affected Ubuntu 8.10 and 9.04. (CVE-2009-1374)

It was discovered that Pidgin did not properly handle certain malformed
messages in the XMPP and Sametime protocol handlers. A remote attacker
could send a specially crafted message and cause Pidgin to crash.
(CVE-2009-1375)

It was discovered that Pidgin did not properly handle certain malformed
messages in the MSN protocol handler. A remote attacker could send a
specially crafted message and possibly execute arbitrary code with user
privileges. (CVE-2009-1376)
