slp.c in the MSN protocol plugin in libpurple in Pidgin before 2.6.6, including 2.6.4, and Adium 1.3.8 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a malformed MSNSLP INVITE request in an SLP message, a different issue than CVE-2010-0013.

Directory traversal vulnerability in slp.c in the MSN protocol plugin in libpurple in Pidgin 2.6.4 and Adium 1.3.8 allows remote attackers to read arbitrary files via a .. (dot dot) in an application/x-msnmsgrp2p MSN emoticon (aka custom smiley) request, a related issue to CVE-2004-0122. NOTE: it could be argued that this is resultant from a vulnerability in which an emoticon download request is processed even without a preceding text/x-mms-emoticon message that announced availability of the emoticon.

The OSCAR protocol plugin in libpurple in Pidgin before 2.6.3 and Adium before 1.3.7 allows remote attackers to cause a denial of service (application crash) via crafted contact-list data for (1) ICQ and possibly (2) AIM, as demonstrated by the SIM IM client.

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.
