CVE-2009-1373
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-2009-1374
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-2009-1375
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-2009-1376
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.";
