CVE-2015-3239

Published: 26 August 2015

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.

Notes

AuthorNote
seth-arnold
I saw nothing in callers of this macro that would prevent
less-than-zero accesses: input params were sometimes integers, sometimes
harder to determine the type. Debian codesearch shows many duplications of
the <= mistake with dwarf_to_unw_regnum arrays in other files, not just the
one dwarf_i.h.

Priority

Low
