Lhaz Unspecified Remote Code Execution Vulnerability

Risk

High

Date Discovered

August 17, 2007

Description

Lhaz is prone to an unspecified remote code-execution vulnerability. An attacker can exploit this issue to execute arbitrary code within the context of the affected application. This issue affects Lhaz 1.33; other versions may also be affected.

Technologies Affected

  • Lhaz Lhaz 1.33

Recommendations

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploitation attempts or activity that results from successful exploitation.

Do not accept or execute files from untrusted or unknown sources.

Do not follow links or open files originating from unknown or untrusted sources.

Implement multiple redundant layers of security.

Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploitation of memory-corruption vulnerabilities.

Run all software as a nonprivileged user with minimal access rights.

If feasible, run all nonadministrative software as a nonadministrative user with the least amount of privileges required to successfully operate. This will limit the potential damage that successful exploitation may achieve.
Currently we are not aware of any vendor-supplied patches for this issue. If you feel we are in error or if you are aware of more recent information, please mail us at: vuldb@securityfocus.com.
