[GLSA-200612-15] McAfee VirusScan: Insecure DT_RPATH

Vulnerability Assessment Summary
McAfee VirusScan: Insecure DT_RPATH

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200612-15
(McAfee VirusScan: Insecure DT_RPATH)

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

A possible hacker could entice a VirusScan user to scan an arbitrary file and
execute arbitrary code with the rights 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 rights of the process invoking VirusScan.

Workaround

Do not scan files or execute VirusScan from an untrusted working
directory.

Solution:
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.
