Insight

Insight

The i386_get_ldt(2) system call allows a process to request that a portion of its Local Descriptor Table be copied from the kernel into userland. The i386_get_ldt(2) syscall performs insufficient validation of its input arguments. In particular, negative or very large values may allow inappropriate data to be copied from the kernel.

Solution

Solution

Upgrade your system to the appropriate stable release or security branch dated after the correction date https://secure1.securityspace.com/smysecure/catid.html?in=FreeBSD-SA-05:07.ldt.asc
