Linux Kernel 2.4.x binfmt_elf.c mmap 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.

A vulnerability classified as critical has been found in Linux Kernel 2.4.x (Operating System). This affects the function mmap of the file binfmt_elf.c. 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:

The binfmt_elf loader (binfmt_elf.c) in Linux kernel 2.4.x up to 2.4.27, and 2.6.x up to 2.6.8, does not properly handle a failed call to the mmap function, which causes an incorrect mapped image and may allow local users to execute arbitrary code.

The bug was discovered 11/10/2004. The weakness was shared 01/10/2005 by Paul Starzetz with isec.pl (Website). It is possible to read the advisory at redhat.com. This vulnerability is uniquely identified as CVE-2004-1071 since 11/29/2004. The exploitability is told to be easy. Attacking locally is a requirement. No form of authentication is needed for exploitation. Technical details and a public exploit are known.

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. The vulnerability was handled as a non-public zero-day exploit for at least 61 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 22609 (Debian DSA-1067-1 : kernel-source-2.4.16 - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l.

Upgrading eliminates this vulnerability. A possible mitigation has been published 2 years after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (18025) and Tenable (22609). The entries 987, 1071, 1085 and 23680 are related to this item.
