BlackBerry vulnerabilities

by Nikola Strahija on January 3rd, 2006 There are two new vulnerabilities that RIM has warned about. BlackBerry users are open for two bugs that could prevent them from opening attachments.

For the first vulnerability there's a workaround at RIM's pages, administrators can apply while waiting for the patch, but it solely prevents TIFF images from being opened.. The bug itself allows an attacker to use a corrupt TIFF image file to cause a heap overflow error that can stop a user's ability to view attachments .

The second vulnerability is exploited by sending malformed protocol packets that cause a denial of service for all BlackBerry Enterprise Server communication. This vulnerability normally applies only to internal users but can be exploited by an external attacker who is able to manipulate DNS queries, RIM said.

The company advised customers to ensure that the BlackBerry Enterprise Server and BlackBerry Router are behind a properly configured firewall to protect them from external attacks. It also advised companies to create static entries in their DNS or hosts tables for the BlackBerry Infrastructure to minimise the risk of DNS hijacking.
