Details
A vulnerability was found in Linux Kernel 2.6.25/2.6.28/2.6.28.1/2.6.28.2/2.6.28.3 (Operating System). It has been declared as problematic. This vulnerability affects an unknown code block. The manipulation with an unknown input leads to a resource management vulnerability. The CWE definition for the vulnerability is CWE-399. As an impact it is known to affect availability. CVE summarizes:
The console selection feature in the Linux kernel 2.6.28 before 2.6.28.4, 2.6.25, and possibly earlier versions, when the UTF-8 console is used, allows physically proximate attackers to cause a denial of service (memory corruption) by selecting a small number of 3-byte UTF-8 characters, which triggers an "an off-by-two memory error." NOTE: it is not clear whether this issue crosses privilege boundaries.
The bug was discovered 01/30/2009. The weakness was presented 03/23/2009 by sgrakkyu (Website). The advisory is shared for download at securityfocus.com. This vulnerability was named CVE-2009-1046 since 03/23/2009. The attack needs to be approached locally. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available.
A public exploit has been developed by sgrakkyu in ANSI C and been published 4 months after the advisory. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 340 days. During that time the estimated underground price was around $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 38668 (Debian DSA-1787-1 : linux-2.6.24 - denial of service/privilege escalation/information leak), 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. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165654 (SUSE Enterprise Linux Security Update Linux Kernel (SUSE-SA:2009:045)).
