ACE archive.

|
|
Ulf Harnhammar discovered that UnAce suffers from buffer overflows
|
|
when testing, unpacking or listing specially crafted ACE archives
|
|
(CAN-2005-0160). He also found out that UnAce is vulnerable to
|
|
directory traversal attacks, if an archive contains "./.." sequences or
|
|
absolute filenames (CAN-2005-0161).
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
An attacker could exploit the buffer overflows to execute
|
|
malicious code or the directory traversals to overwrite arbitrary
|
|
files.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All UnAce users should upgrade to the latest available 1.2
|
|
version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-arch/unace-1.2b-r1"</code>
