DESCRIPTION:
Multiple vulnerabilities have been reported in Pidgin, which can be
exploited by malicious people to manipulate certain data, cause a DoS
(Denial of Service), and compromise a user's system.

1) An error within the MXit protocol plugin when saving images can be
exploited to overwrite certain files.

2) A boundary error within the "mxit_cb_http_read()" function
(libpurple/protocols/mxit/http.c) when parsing incoming HTTP headers
can be exploited to cause a stack-based buffer overflow via a
specially crafted HTTP header.

Successful exploitation of this vulnerability may allow execution of
arbitrary code.

3) An error within the "mw_prpl_normalize()" function
(libpurple/protocols/sametime/sametime.c) when handling user ID
longer than 4096 bytes can be exploited to cause a crash.

4) Some errors within the "upnp_parse_description_cb()", 
"purple_upnp_discover_send_broadcast()", "looked_up_public_ip_cb()",
"looked_up_internal_ip_cb()", "purple_upnp_set_port_mapping()", and
"purple_upnp_remove_port_mapping()" functions (libpurple/upnp.c) when
handling UPnP requests can be exploited to cause crashes.

The vulnerabilities are reported in version 2.10.6. Prior versions
may also be affected.

SOLUTION:
Update to version 2.10.7.
