Signature Detail

APP: Novell eDirectory Monitored Events Overflow

This signature detects attempts to exploit known buffer overflow and invalid-free vulnerabilities in Novell eDirectory. They are due to insufficient bound checking on a user-supplied buffer length value or referencing a value outside of an array. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the Novell eDirectory server.

Extended Description

The Novell eDirectory server is prone to buffer-overflow and invalid-free vulnerabilities because it fails to perform sufficient bounds checking on client-supplied data before copying it to a buffer or referencing a value outside of an array. An attacker could leverage these issues to have arbitrary code execute with administrative privileges. A successful exploit could result in a denial of service or code execution, possibly leading to the complete compromise of the affected system. eDirectory 8.8/8.8.1 are vulnerable to these issues; prior versions may be affected as well.
