<description>
|
|
<p>
|
|
unarj has a bounds checking vulnerability within the handling of
|
|
long filenames in archives. It also fails to properly sanitize paths
|
|
when extracting an archive (if the "x" option is used to preserve
|
|
paths).
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
An attacker could trigger a buffer overflow or a path traversal by
|
|
enticing a user to open an archive containing specially-crafted path
|
|
names, potentially resulting in the overwrite of files or execution of
|
|
arbitrary code with the permissions of the user running unarj.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All unarj users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-arch/unarj-2.63a-r2"</code>
