CPNI, CERT-FI, Tim Kientzle, and Colin Percival reported a buffer
|
|
overflow (CVE-2007-3641), an infinite loop (CVE-2007-3644), and a NULL
|
|
pointer dereference (CVE-2007-3645) within the processing of archives
|
|
having corrupted PaX extension headers.

<impact type="normal">
|
|
<p>
|
|
An attacker can trick a user or automated system to process an archive
|
|
with malformed PaX extension headers into execute arbitrary code, crash
|
|
an application using the library, or cause a high CPU load.
|
|
</p>

<workaround>
