Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D EnergyMech is an IRC bot programmed in C. Affected packages =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-irc/emech < 3.0.2 >=3D 3.0.2 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D A bug in EnergyMech fails to handle empty CTCP NOTICEs correctly, and will cause a crash from a segmentation fault. Impact =3D=3D=3D=3D=3D=3D By sending an empty CTCP NOTICE, a remote attacker could exploit this vulnerability to cause a Denial of Service. 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 EnergyMech users should update to the latest stable version: # emerge --sync # emerge --ask --oneshot --verbose ">=3Dnet-irc/emech-3.0.2" References =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [ 1 ] EnergyMech Changelog http://www.energymech.net/versions-3.0.html 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-200606-26.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.
