Description

Integer signedness error in the sockargs function in sys/kern/uipc_syscalls.c in FreeBSD 10.1 before p34, 10.2 before p17, and 10.3 before p3 allows local users to cause a denial of service (memory overwrite and kernel panic) or gain privileges via a negative buflen argument, which triggers a heap-based buffer overflow.

Solution(s)

  • freebsd-upgrade-base-10_1-release-p34
  • freebsd-upgrade-base-10_2-release-p17
  • freebsd-upgrade-base-10_3-release-p3
