Linux Kernel up to 2.6.12 random.c poolsize_strategy 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 was found in Linux Kernel (Operating System) and classified as critical. This issue affects the function poolsize_strategy of the file random.c. 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:

Multiple integer signedness errors in the sg_scsi_ioctl function in scsi_ioctl.c for Linux 2.6.x allow local users to read or modify kernel memory via negative integers in arguments to the scsi ioctl, which bypass a maximum length check before calling the copy_from_user and copy_to_user functions.

The weakness was presented 01/11/2005 by Brad Spengler (spender) with grsecurity (Website). It is possible to read the advisory at secunia.com. The identification of this vulnerability is CVE-2005-0180 since 01/28/2005. The attack needs to be initiated within the local network. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability scanner Nessus provides a plugin with the ID 20450 (Mandrake Linux Security Advisory : kernel (MDKSA-2005:219)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Mandriva Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 115055 (Linux Kernel Multiple Vulnerabilities (RHSA-2005:092-14)).

Upgrading eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at ftp.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published 12 months after the disclosure of the vulnerability.
