Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Xlockmore is just another screensaver application for X. Affected packages =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 x11-misc/xlockmore < 5.43 >=3D 5.43 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D A Denial of Service flaw was found in the way Xlockmore performed the passing of arguments to the underlying localtime() call, when the 'dlock' mode was used. Impact =3D=3D=3D=3D=3D=3D A local attacker could possibly cause a Denial of Service condition and potentially obtain unauthorized access to the graphical session, previously locked by another user. Workaround =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D There is no known workaround at this time. Resolution =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D All Xlockmore users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=3Dx11-misc/xlockmore-5.43" References =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [ 1 ] CVE-2012-4524 http://nvd.nist.gov/nvd.cfm?cvename=3DCVE-2012-4524 [ 2 ] CVE-2013-4143 http://nvd.nist.gov/nvd.cfm?cvename=3DCVE-2013-4143 Availability =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201309-03.xml Concerns? =3D=3D=3D=3D=3D=3D=3D=3D=3D Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us.
