Novell NetIQ Access Manager dhost Service Shared Memory Section Out-Of-Bounds Read Information Disclosure Vulnerability
Vulnerability Details
This vulnerability allows local attackers to disclose sensitive information on vulnerable installations of Novell NetIQ Access Manager. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the processing of information in a shared memory section by the dhost service. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this in conjunction with other vulnerabilities to escalate privileges to the context of SYSTEM.
