<p>libxml2 is the XML C parser and toolkit developed for the Gnome project.</p> |

<description> |
| 39 |
<p>The "xmlStringLenDecodeEntities()" function in parser.c contains a |
| 40 |
boundary error which could possibly cause a heap-based buffer overflow. |

<impact type="normal"> |
| 44 |
<p>A remote attacker could entice a user to open a specially crafted XML |
| 45 |
file in an application linked against libxml2, possibly resulting in the |
| 46 |
remote execution of arbitrary code with the permissions of the user |
| 47 |
running the application, or Denial of Service. |
| 48 |
</p> |
| 49 |
</impact> |
| 50 |
<workaround> |
| 51 |
<p>There is no known workaround at this time.</p> |
| 52 |
</workaround> |
| 53 |
<resolution> |
| 54 |
<p>All libxml2 users should upgrade to the latest version:</p> |
| 55 |
|
| 56 |
<code> |
| 57 |
# emerge --sync |
| 58 |
# emerge --ask --oneshot --verbose ">=dev-libs/libxml2-2.7.8-r4" |
| 59 |
</code> |
| 60 |
|
| 61 |
<p>Packages which depend on this library may need to be recompiled. Tools |
| 62 |
such as revdep-rebuild may assist in identifying some of these packages. |
| 63 |
