26 May 2009 — 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.

26 May 2009 — 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.

26 May 2009 — 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.

01 Oct 2007 — libpurple in Pidgin before 2.2.1 does not properly handle MSN nudge messages from users who are not on the receiver's buddy list, which allows remote attackers to cause a denial of service (crash) via a nudge message that triggers an access of "an invalid memory location." libpurple de Pidgin versiones anteriores a 2.2.1 no gestiona apropiadamente los mensajes personalizados de usuarios que no están en la lista de amigos del receptor, lo cual permite a atacantes remotos provocar una denegación de servicio (... • http://fedoranews.org/updates/FEDORA-2007-236.shtml •
