Description

Integer signedness error in the amd64_set_ldt function in sys/amd64/amd64/sys_machdep.c in FreeBSD 9.3 before p39, 10.1 before p31, and 10.2 before p14 allows local users to cause a denial of service (kernel panic) via an i386_set_ldt system call, which triggers a heap-based buffer overflow.

Solution(s)

  • freebsd-upgrade-base-10_1-release-p31
  • freebsd-upgrade-base-10_2-release-p14
  • freebsd-upgrade-base-9_3-release-p39
