<background>
|

|
<p>RAR and UnRAR provide command line interfaces for compressing and decompressing RAR files.</p>
|

|

|
<description>
|
||
|
<p>Due to an error in the validation of symbolic links within archives, RAR and UnRAR can potentially write files to a directory which is outside of the intended unpack directory.</p>
|

|
</description>
|
||
|
<impact type="normal">
|
||
|
<p>If the user running RAR or UnRAR extracts a malicious archive, the archive could overwrite a file such as the user's shell initialization scripts, potentially resulting in arbitrary code execution in the context of that user.</p>

</impact>
|

<workaround>
|

|
<p>There is no known workaround at this time.</p>
