FreeBSD 7.0/7.1 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.

Summaryinfo

A vulnerability marked as problematic has been reported in FreeBSD 7.0/7.1. This impacts an unknown function. The manipulation leads to memory corruption. This vulnerability is listed as CVE-2008-3531. In addition, an exploit is available.

Detailsinfo

A vulnerability was found in FreeBSD 7.0/7.1 (Operating System) and classified as critical. This issue affects an unknown code. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow in sys/kern/vfs_mount.c in the kernel in FreeBSD 7.0 and 7.1, when vfs.usermount is enabled, allows local users to gain privileges via a crafted (1) mount or (2) nmount system call, related to copying of "user defined data" in "certain error conditions."

The weakness was presented 09/05/2008 (Website). It is possible to read the advisory at security.FreeBSD.org. The identification of this vulnerability is CVE-2008-3531 since 08/07/2008. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Patroklos Argyroudis in ANSI C and been published 11 months after the advisory. The exploit is available at securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (45143), Exploit-DB (9082), SecurityFocus (BID 31002†), SecurityTracker (ID 1020816†) and Vulnerability Center (SBV-39881†).
