Red Hat Linux up to 5.1 Mountd memory corruption

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as critical, was found in Red Hat Linux up to 5.1 (Operating System). This affects an unknown part of the component Mountd. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in NFS mountd gives root access to remote attackers, mostly in Linux systems.

The weakness was released 10/12/1998 by LINUX as not defined posting (Bugtraq). The advisory is shared at securityfocus.com. This vulnerability is uniquely identified as CVE-1999-0002. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed in ANSI C. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 11337 (Multiple Linux rpc.mountd Remote Overflow), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gain a shell remotely and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 66001 (mountd NFS Service Buffer Overflow Vulnerability).

Upgrading eliminates this vulnerability. Attack attempts may be identified with Snort ID 315.

The vulnerability is also documented in the databases at X-Force (1411), Exploit-DB (19096), Tenable (11337), SecurityFocus (BID 121†) and Vulnerability Center (SBV-538†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
