The default configuration of the <Button2> binding in Uzbl before 2010.08.05 does not properly use the @SELECTED_URI feature, which allows user-assisted remote attackers to execute arbitrary commands via a crafted HREF attribute of an A element in an HTML document.

The remote host is affected by the vulnerability described in GLSA-201412-08 (Multiple packages, Multiple vulnerabilities fixed in 2010)

    A context-dependent attacker may be able to gain escalated privileges,       execute arbitrary code, cause Denial of Service, obtain sensitive       information, or otherwise bypass security restrictions.
  Workaround :

    There are no known workarounds at this time.

Fix a bug in the default configuration for the mouse bindings that can allow crafted links to execute arbitrary shell code. Please check your local configuration and replace '\@SELECTED_URI' with '$8' in any string that is executed as shell code (usually involves 'sh 'commands_here').
