<p>
|
|
Yuuichi Teranishi discovered a flaw in libxml2 versions prior to 2.6.6.
|
|
When the libxml2 library fetches a remote resource via FTP or HTTP, libxml2
|
|
uses parsing routines that can overflow a buffer caused by improper bounds
|
|
checking if they are passed a URL longer than 4096 bytes.
|
|
</p>
|
|

|
<impact type="normal">
|
|
<p>
|
|
If an attacker is able to exploit an application using libxml2 that parses
|
|
remote resources, then this flaw could be used to execute arbitrary code.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
No workaround is available; users are urged to upgrade libxml2 to 2.6.6.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All users are recommended to upgrade their libxml2 installation:
|
|
</p>
|
|
<code>
|
|
# emerge sync
|
|
# emerge -pv ">=dev-libs/libxml2-2.6.6"
|
|
# emerge ">=dev-libs/libxml2-2.6.6"</code>
|
|
</resolution>
