Subject: libunwind: update to 1.2
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5d48dc1146171520445c43ee894d9dfce09ae4e2;p=openwrt%2Fstaging%2Fblogic.git

libunwind: update to 1.2

Addresses CVE-2015-3239: Off-by-one error in the dwarf_to_unw_regnum
function in include/dwarf_i.h in libunwind 1.1 allows local users to
have unspecified impact via invalid dwarf opcodes.

Upstream stable-v1.2 fixed the missing unwind_i.h issue but no new
tarball is released yet
