| <p> |
| KVIrc is a free portable IRC client based on Qt. |
| </p> |

| <description> |
| <p> |
| Stefan Cornelius from Secunia Research discovered that the |
| "parseIrcUrl()" function in file src/kvirc/kernel/kvi_ircurl.cpp does |
| not properly sanitise parts of the URI when building the command for |
| KVIrc's internal script system. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could entice a user to open a specially crafted |
| irc:// URI, possibly leading to the remote execution of arbitrary code |
| with the privileges of the user running KVIrc. Successful exploitation |
| requires that KVIrc is registered as the default handler for irc:// or |
| similar URIs. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All KVIrc users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-irc/kvirc-3.2.6_pre20070714"</code> |
