Synopsis :

The remote host is running an instant messaging client that is
affected by multiple buffer overflow vulnerabilities.

Description :

The remote host is running Pidgin earlier than 2.5.6. Such versions
are reportedly affected by multiple buffer overflow vulnerabilities :

- A buffer overflow is possible when initiating a file
transfer to a malicious buddy over XMPP. (CVE-2009-1373)

- A buffer overflow issue in the 'decrypt_out()' function
can be exploited through specially crafted 'QQ' packets.
(CVE-2009-1374)

- A buffer maintained by PurpleCircBuffer which is used by
XMPP and Sametime protocol plugins can be corrupted if
it's exactly full and then more bytes are added to it.
(CVE-2009-1375)

- An integer-overflow issue exists in the application due
to an incorrect typecasting of 'int64' to 'size_t'.
(CVE-2009-1376)
