CVE-2010-0277
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.

CVE-2010-0420
libpurple in Finch in Pidgin before 2.6.6, when an XMPP multi-user
chat (MUC) room is used, does not properly parse nicknames containing
<br> sequences, which allows remote attackers to cause a denial of
service (application crash) via a crafted nickname.

CVE-2010-0423
gtkimhtml.c in Pidgin before 2.6.6 allows remote attackers to cause a
denial of service (CPU consumption and application hang) by sending
many smileys in a (1) IM or (2) chat.");
