Malicious Code Circulating via Israel/Hamas Conflict Spam Messages
added January 9, 2009 at 09:25 am
US-CERT is aware of public reports of malicious code circulating via spam email messages related to the Israel/Hamas conflict in Gaza. These messages may contain factual information about the conflict and appear to come from CNN. Additionally, the messages indicate that additional news coverage of the conflict can be viewed by following a link provided in the email body. If users click on this link, they are redirected to a bogus CNN website that appears to contain a video. Users who attempt to view this video will be prompted to update to a new version of Adobe Flash Player in order to view the video. This update is not a legitimate Adobe Flash Player update; it is malicious code. If users download this executable file, malicious code may be installed on their systems.
US-CERT encourages users and administrators to take the following preventative measures to help mitigate the security risks:
- Install antivirus software, and keep the virus signatures up to date.
- Do not follow unsolicited links and do not open unsolicited email messages.
- Use caution when visiting untrusted websites.
- Use caution when downloading and installing applications.
- Obtain software applications and updates directly from the vendor's website.
- Refer to the Recognizing and Avoiding Email Scams (pdf) document for more information on avoiding email scams.
- Refer to the Avoiding Social Engineering and Phishing Attacks document for more information on social engineering attacks.

OpenSSL Releases Security Advisory
added January 8, 2009 at 08:47 am
The OpenSSL project has released a Security Advisory to address a vulnerability in OpenSSL. This vulnerability results from several incorrect checks of the result of the EVP_VerifyFinal function when performing signature checks on DSA and ECDSA keys used with SSL/TLS. As a result, a malformed signature could be treated as valid. Exploitation of this vulnerability may allow a remote attacker to bypass signature checks and conduct spoofing attacks.
US-CERT encourages users and administrators to review the OpenSSL Security Advisory and apply any vendor released updates for the OpenSSL package or upgrade to the newest version of the software as described in the OpenSSL advisory.
