Details

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.
