| <description> |
| <p> |
| Lionel Elie Mamane discovered an error in c2faxrecv, which doesn't |
| properly sanitize TSI strings when handling incoming calls. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| A remote attacker can send null (\0) and shell metacharacters in the |
| TSI string from an anonymous fax number, leading to the execution of |
| arbitrary code with the rights of the user running c2faxrecv. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All CAPI4Hylafax users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-misc/capi4hylafax-01.03.00.99.300.3-r1"</code> |
