Medium: gdb

Issue Overview:

GDB tried to auto-load certain files (such as GDB scripts, Python scripts, and a thread debugging library) from the current working directory when debugging programs. This could result in the execution of arbitrary code with the user’s privileges when GDB was run in a directory that has untrusted content. (CVE-2011-4355)

With this update, GDB no longer auto-loads files from the current directory and only trusts certain system directories by default. The list of trusted directories can be viewed and modified using the “show auto-load safe-path” and “set auto-load safe-path” GDB commands. Refer to the GDB manual, linked to in the References, for further information.
