Publication date

30 April 2014

Overview

elfutils could be made to crash or run programs if it processed a specially crafted file.

Releases

Packages

  • elfutils - collection of utilities to handle ELF objects

Details

Florian Weimer discovered that the elfutils libdw library incorrectly
handled malformed compressed debug sections in ELF files. If a user or
automated system were tricked into processing a specially crafted ELF file,
applications linked against libdw could be made to crash, or possibly
execute arbitrary code.
