Detailsinfo

A vulnerability has been found in Linux Kernel 2.6.23 (Operating System) and classified as critical. Affected by this vulnerability is the function ibwdt_ioctl. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Buffer underflow in the ibwdt_ioctl function in drivers/watchdog/ib700wdt.c in the Linux kernel before 2.6.28-rc1 might allow local users to have an unknown impact via a certain /dev/watchdog WDIOC_SETTIMEOUT IOCTL call.

The bug was discovered 12/10/2008. The weakness was published 12/22/2008 (Website). The advisory is shared at xforce.iss.net. This vulnerability is known as CVE-2008-5702 since 12/22/2008.
