(CVE-2012-3509) Alexander Cherepanov and Hanno Böck discovered multiple additional out-of-bounds reads and writes in GNU binutils. An attacker could use these to craft input that could cause a denial of service (application crash) or possibly execute arbitrary code. A few of these issues may be limited in exposure to a denial of service (application abort) by the GNU C library's Fortify Source printf protection. The strings(1) utility in GNU binutils used libbfd by default when examining executable object files; unfortunately, libbfd was not originally developed with the expectation of hostile input. As a defensive measure, the behavior of strings has been changed to default to 'strings --all' behavior, which does not use libbfd; use the new argument to strings, '--data', to recreate the old behavior.
