| <synopsis> |

| potentially allowing the execution of arbitrary code. |

| <p> |
| 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. |
| </p> |
| </background> |
| <description> |
| <p> |
| 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. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| Successful exploitation would result in the execution of arbitrary code |
| on loading a specially crafted object file or the execution of |
| arbitrary commands. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All gdb users should upgrade to the latest stable version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=sys-devel/gdb-6.3-r3"</code> |
| </resolution> |
