<title>McAfee VirusScan: Insecure DT_RPATH</title>
|
|
<synopsis>
|
|
McAfee VirusScan for Linux is distributed with an insecure DT_RPATH,
|
|
potentially allowing a remote attacker to execute arbitrary code.

|
Jakub Moc of Gentoo Linux discovered that McAfee VirusScan was
|
|
distributed with an insecure DT_RPATH which included the current
|
|
working directory, rather than $ORIGIN which was probably intended.

<impact type="high">
|
|
<p>
|
|
An attacker could entice a VirusScan user to scan an arbitrary file and
|
|
execute arbitrary code with the privileges of the VirusScan user by
|
|
tricking the dynamic loader into loading an untrusted ELF DSO. An
|
|
automated system, such as a mail scanner, may be subverted to execute
|
|
arbitrary code with the privileges of the process invoking VirusScan.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Do not scan files or execute VirusScan from an untrusted working
|
|
directory.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
As VirusScan verifies that it has not been modified before executing,
|
|
it is not possible to correct the DT_RPATH. Furthermore, this would
|
|
violate the license that VirusScan is distributed under. For this
|
|
reason, the package has been masked in Portage pending the resolution
|
|
of this issue.
