Ubuntu 7.10 / 8.04 LTS : pidgin vulnerabilities (USN-675-1)

Ubuntu Security Notice (C) 2008-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

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
man-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).

Note that Tenable Network Security has extracted the preceding
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.

Solution :

Update the affected packages.
