"Security vulnerabilities has been identified and fixed in pidgin :

The NSS plugin in libpurple in Pidgin 2.4.1 does not verify SSL
certificates, which makes it easier for remote attackers to trick a
user into accepting an invalid server certificate for a spoofed
service. (CVE-2008-3532)

Pidgin 2.4.1 allows remote attackers to cause a denial of service
(crash) via a long filename that contains certain characters, as
demonstrated using an MSN message that triggers the crash in the
msn_slplink_process_msg function. (CVE-2008-2955)

The UPnP functionality in Pidgin 2.0.0, and possibly other versions,
allows remote attackers to trigger the download of arbitrary files and
cause a denial of service (memory or disk consumption) via a UDP
packet that specifies an arbitrary URL. (CVE-2008-2957)

Buffer overflow in the XMPP SOCKS5 bytestream server in Pidgin
(formerly Gaim) before 2.5.6 allows remote authenticated users to
execute arbitrary code via vectors involving an outbound XMPP file
transfer. NOTE: some of these details are obtained from third-party
information (CVE-2009-1373).

Buffer overflow in the decrypt_out function in Pidgin (formerly Gaim)
before 2.5.6 allows remote attackers to cause a denial of service
(application crash) via a QQ packet (CVE-2009-1374).

The PurpleCircBuffer implementation in Pidgin (formerly Gaim) before
2.5.6 does not properly maintain a certain buffer, which allows remote
attackers to cause a denial of service (memory corruption and
application crash) via vectors involving the (1) XMPP or (2) Sametime
protocol (CVE-2009-1375).

Multiple integer overflows in the msn_slplink_process_msg functions in
the MSN protocol handler in (1) libpurple/protocols/msn/slplink.c and
(2) libpurple/protocols/msnp9/slplink.c in Pidgin (formerly Gaim)
before 2.5.6 on 32-bit platforms allow remote attackers to execute
arbitrary code via a malformed SLP message with a crafted offset
value, leading to buffer overflows. NOTE: this issue exists because of
an incomplete fix for CVE-2008-2927 (CVE-2009-1376).

The OSCAR protocol implementation in Pidgin before 2.5.8 misinterprets
the ICQWebMessage message type as the ICQSMS message type, which
allows remote attackers to cause a denial of service (application
crash) via a crafted ICQ web message that triggers allocation of a
large amount of memory (CVE-2009-1889).

The msn_slplink_process_msg function in
libpurple/protocols/msn/slplink.c in libpurple, as used in Pidgin
(formerly Gaim) before 2.5.9 and Adium 1.3.5 and earlier, allows
remote attackers to execute arbitrary code or cause a denial of
service (memory corruption and application crash) by sending multiple
crafted SLP (aka MSNSLP) messages to trigger an overwrite of an
arbitrary memory location. NOTE: this issue reportedly exists because
of an incomplete fix for CVE-2009-1376 (CVE-2009-2694).

Unspecified vulnerability in Pidgin 2.6.0 allows remote attackers to
cause a denial of service (crash) via a link in a Yahoo IM
(CVE-2009-3025)

protocols/jabber/auth.c in libpurple in Pidgin 2.6.0, and possibly
other versions, does not follow the require TLS/SSL preference when
connecting to older Jabber servers that do not follow the XMPP
specification, which causes libpurple to connect to the server without
the expected encryption and allows remote attackers to sniff sessions
(CVE-2009-3026).

libpurple/protocols/irc/msgs.c in the IRC protocol plugin in libpurple
in Pidgin before 2.6.2 allows remote IRC servers to cause a denial of
service (NULL pointer dereference and application crash) via a TOPIC
message that lacks a topic string (CVE-2009-2703).

The msn_slp_sip_recv function in libpurple/protocols/msn/slp.c in the
MSN protocol plugin in libpurple in Pidgin before 2.6.2 allows remote
attackers to cause a denial of service (NULL pointer dereference and
application crash) via an SLP invite message that lacks certain
required fields, as demonstrated by a malformed message from a KMess
client (CVE-2009-3083).

The msn_slp_process_msg function in libpurple/protocols/msn/slpcall.c
in the MSN protocol plugin in libpurple 2.6.0 and 2.6.1, as used in
Pidgin before 2.6.2, allows remote attackers to cause a denial of
service (application crash) via a handwritten (aka Ink) message,
related to an uninitialized variable and the incorrect UTF16-LE
charset name (CVE-2009-3084).

The XMPP protocol plugin in libpurple in Pidgin before 2.6.2 does not
properly handle an error IQ stanza during an attempted fetch of a
custom smiley, which allows remote attackers to cause a denial of
service (application crash) via XHTML-IM content with cid: images
(CVE-2009-3085).

This update provides pidgin 2.6.2, which is not vulnerable to these
issues."
