Details
A vulnerability classified as problematic has been found in Linux Kernel 2.6.10/2.6.11 Rc1 Bk6 (Operating System). Affected is some unknown processing of the component i2c-viapro Driver. The manipulation with an unknown input leads to a heap-based overflow vulnerability. CWE is classifying the issue as CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). This is going to have an impact on confidentiality. CVE summarizes:
Linux kernel 2.6.10 and 2.6.11rc1-bk6 uses different size types for offset arguments to the proc_file_read and locks_read_proc functions, which leads to a heap-based buffer overflow when a signed comparison causes negative integers to be used in a positive context.
The bug was discovered 02/15/2005. The weakness was shared 02/15/2005 by Jean Delvare (Website). The advisory is shared for download at kernel.org. This vulnerability is traded as CVE-2005-0529 since 02/24/2005. Access to the local network is required for this attack to succeed. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available.
The vulnerability was handled as a non-public zero-day exploit for at least 53 days. During that time the estimated underground price was around $5k-$25k.
