accounts on multiple instant messaging networks simultaneously.

implementation handled MSNSLP invitations. A remote attacker could send a
specially-crafted INVITE request that would cause a denial of service
(memory corruption and Pidgin crash). (CVE-2010-0277)

for responsibly reporting the CVE-2010-0420 issue.
