"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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
