Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D MPFR is a library for multiple-precision floating-point computations with exact rounding. Affected packages =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/mpfr < 3.1.3_p4 >=3D 3.1.3_p4 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D MPFR fails to adequately check user-supplied input, which could lead to a buffer overflow. Impact =3D=3D=3D=3D=3D=3D A remote attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition. 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 MPFR users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=3Ddev-libs/mpfr-3.1.3_p4" References =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [ 1 ] CVE-2014-9474 http://nvd.nist.gov/nvd.cfm?cvename=3DCVE-2014-9474 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/201512-06 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.
