Description

The ucode_ioctl function in intel/io/ucode_drv.c in Sun Solaris 10 and OpenSolaris snv_69 through snv_133, when running on x86 architectures, allows local users to cause a denial of service (panic) via a request with a 0 size value to the UCODE_GET_VERSION IOCTL, which triggers a NULL pointer dereference in the ucode_get_rev function, related to retrieval of the microcode revision.

We'll keep you safe. Trust us, that's our job. Even though, contrary to what our Avatar might imply, we're not all linebackers. In fact, some of us are quite petite. And others of us wear high heeled boots. Red. Wondering whether we also know what we're talking about? C'mon -have you read any of these security posts?
