Title: elfutils: Heap-based buffer overflow
Date: December 13, 2016
Bugs: #507246
ID: 201612-32
– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –
Synopsis
========
A heap-based buffer overflow vulnerability in elfutils might allow
remote attackers to execute arbitrary code.
Background
==========
Elfutils provides a library and utilities to access, modify and analyse
ELF objects.
Affected packages
=================
——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 dev-libs/elfutils < 0.159 >= 0.159
Description
===========
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.
Impact
======
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.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All elfutils users should upgrade to the latest version:
# emerge –sync
# emerge –ask –oneshot –verbose “>=dev-libs/elfutils-0.159”
