Linux Kernel up to 2.4.27/2.6.8 ELF Binary Loader denial of service

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 up to 2.4.27/2.6.8 (Operating System). It has been classified as problematic. This affects an unknown function of the component ELF Binary Loader. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on confidentiality. The summary by CVE is:

The open_exec function in the execve functionality (exec.c) in Linux kernel 2.4.x up to 2.4.27, and 2.6.x up to 2.6.8, allows local users to read non-readable ELF binaries by using the interpreter (PT_INTERP) functionality.

The bug was discovered 04/11/2005. The weakness was disclosed 11/10/2004 by Paul Starzetz with iSEC Security Research (Website). It is possible to read the advisory at isec.pl. This vulnerability is uniquely identified as CVE-2004-1073 since 11/29/2004. The attack needs to approached within the local network. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available.

The exploit is shared for download at isec.pl. 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 21923 (CentOS 3 : kernel (CESA-2005:293)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117967 (CentOS Security Update for Kernel (CESA-2005:293)).

Upgrading eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at kernel.org. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published 6 months after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (18025), Exploit-DB (624), Tenable (21923), SecurityFocus (BID 11646†) and OSVDB (11600†). The entries VDB-947, VDB-945, VDB-946 and VDB-944 are pretty similar. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
