| <description> |
| <p> |
| 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. |
