| Descripción: | Summary:
The remote host is missing an update for the 'finch'
package(s) announced via the referenced advisory.
Vulnerability Insight:
Pidgin is an instant messaging program which can log in to multiple
accounts on multiple instant messaging networks simultaneously.
An input sanitization flaw was found in the way Pidgin's MSN protocol
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)
A denial of service flaw was found in Finch's XMPP chat implementation,
when using multi-user chat. If a Finch user in a multi-user chat session
were to change their nickname to contain the HTML 'br' element, it would
cause Finch to crash. (CVE-2010-0420)
Red Hat would like to thank Sadrul Habib Chowdhury of the Pidgin project
for responsibly reporting the CVE-2010-0420 issue.
A denial of service flaw was found in the way Pidgin processed emoticon
images. A remote attacker could flood the victim with emoticon images
during mutual communication, leading to excessive CPU use. (CVE-2010-0423)
These packages upgrade Pidgin to version 2.6.6. Refer to the linked Pidgin release
notes for a full list of changes.
