Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Fossil is a simple, high-reliability, distributed software configuration management system. Affected packages =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-vcs/fossil < 2.4 >=3D 2.4 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Fossil does not properly validate SSH sync protocol URLs. Impact =3D=3D=3D=3D=3D=3D A remote attacker, by enticing a user to open a specially crafted URL, could possibly execute arbitrary commands with the privileges of the user running the application. 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 Fossil users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=3Ddev-vcs/fossil-2.4" References =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [ 1 ] CVE-2017-17459 https://nvd.nist.gov/vuln/detail/CVE-2017-17459 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: https://security.gentoo.org/glsa/201801-20 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.
