CVE-2006-6013 Information

Description

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.
