Discussion

Linux Kernel CapiUtil.c Buffer Overflow Vulnerability

The Linux kernel is prone to a local buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before using into an insufficiently sized buffer.

An attacker can exploit this issue to execute arbitrary code with kernel-level privileges or cause the affected kernel to crash, denying service to legitimate users.

This issue affects versions 2.6.9 to 2.6.20 and the 'isdn4k-utils' utilities.
