Integer signedness error in the fw_ioctl (FW_IOCTL) function in the FireWire (IEEE-1394) drivers (dev/firewire/fwdev.c) in various BSD kernels, including DragonFlyBSD, FreeBSD 5.5, MidnightBSD 0.1-CURRENT before 20061115, NetBSD-current before 20061116, NetBSD-4 before 20061203, and TrustedBSD, allows local users to read arbitrary memory contents via certain negative values of crom_buf->len in an FW_GCROM command. NOTE: this issue has been labeled as an integer overflow, but it is more like an integer signedness error.

Security readout for executives and security teams

CVE-2006-6013 is a local information disclosure flaw in BSD FireWire kernel drivers. A logged-in local user could make the kernel return memory contents it should not expose. The cited sources do not show remote exploitation or active exploitation. Exposure is most likely on legacy BSD systems with FireWire kernel support and local user access. Internet-facing exposure is not indicated by the bundle. Modern systems are unlikely to be affected unless they run old or derivative BSD kernels containing the vulnerable driver code. Treat this as a legacy local-risk issue. It is important for old BSD systems with shared user access, but the provided evidence does not support emergency internet-wide response. Mitigation focus: Apply relevant BSD vendor security updates, including FreeBSD-SA-06:25 where applicable.; Update NetBSD branches beyond the fixed dates listed in the CVE record.; Check DragonFlyBSD, MidnightBSD, and TrustedBSD guidance before assuming patched status..
