elfutils: Heap-based buffer overflow

elfutils: Heap-based buffer overflow A heap-based buffer overflow vulnerability in elfutils might allow remote attackers to execute arbitrary code. elfutils 2016-12-13 2016-12-13: 2 507246 remote 0.159 0.159

Elfutils provides a library and utilities to access, modify and analyse ELF objects.

An integer overflow, in the check_section function of dwarf_begin_elf.c, in the libdw library can lead to a heap-based buffer overflow.

A remote attacker could entice a user to open a specially crafted file, possibly resulting in the execution of arbitrary code with the privileges of the process or a Denial of Service condition.

There is no known workaround at this time.

All elfutils users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-libs/elfutils-0.159"
