Multiple vulnerabilities have been discovered in the GNU debugger, potentially allowing the execution of arbitrary code.
gdb is the GNU project's debugger, facilitating the analysis and debugging of applications. The BFD library provides a uniform method of accessing a variety of object file formats.
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered an integer overflow in the BFD library, resulting in a heap overflow. A review also showed that by default, gdb insecurely sources initialisation files from the working directory.
Successful exploitation would result in the execution of arbitrary code on loading a specially crafted object file or the execution of arbitrary commands.
There is no known workaround at this time.
All gdb users should upgrade to the latest stable version:
