<p>
|
|
An anonymous researcher discovered a file descriptor leak error in the
|
|
processing of CAB archives and a lack of validation of the "id"
|
|
parameter string used to create local files when parsing MIME headers.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A remote attacker can send several crafted CAB archives with a
|
|
zero-length record header that will fill the available file descriptors
|
|
until no other is available, which will prevent ClamAV from scanning
|
|
most archives. An attacker can also send an email with specially
|
|
crafted MIME headers to overwrite local files with the permissions of
|
|
the user running ClamAV, such as the virus database file, which could
|
|
prevent ClamAV from detecting any virus.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
The first vulnerability can be prevented by refusing any file of type
|
|
CAB, but there is no known workaround for the second issue.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All ClamAV users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-antivirus/clamav-0.90"</code>
|
|
</resolution>
