"Fabian Yamaguchi discovered that Pidgin incorrectly validated all
fields of an incoming message in the MSN protocol handler. A remote
attacker could send a specially crafted message and cause Pidgin to
crash, leading to a denial of service. (CVE-2010-0277)

Sadrul Habib Chowdhury discovered that Pidgin incorrectly handled
certain nicknames in Finch group chat rooms. A remote attacker could
use a specially crafted nickname and cause Pidgin to crash, leading to
a denial of service. (CVE-2010-0420)

Antti Hayrynen discovered that Pidgin incorrectly handled large
numbers of smileys. A remote attacker could send a specially crafted
message and cause Pidgin to become unresponsive, leading to a denial
of service. (CVE-2010-0423).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
