Details

It was discovered that Pidgin did not properly handle certain malformed
messages in the MSN protocol handler. A remote attacker could send a specially
crafted message and possibly execute arbitrary code with user privileges.
(CVE-2008-2927)

It was discovered that Pidgin did not properly handle file transfers containing
a long filename and special characters in the MSN protocol handler. A remote
attacker could send a specially crafted filename in a file transfer request
and cause Pidgin to crash, leading to a denial of service. (CVE-2008-2955)

It was discovered that Pidgin did not impose resource limitations in the UPnP
service. A remote attacker could cause Pidgin to download arbitrary files
and cause a denial of service from memory or disk space exhaustion.
(CVE-2008-2957)

It was discovered that Pidgin did not validate SSL certificates when using a
secure connection. If a remote attacker were able to perform a
machine-in-the-middle attack, this flaw could be exploited to view sensitive
information. This update alters Pidgin behaviour by asking users to confirm
the validity of a certificate upon initial login. (CVE-2008-3532)
