Background =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D GCC-XML is an XML output extension to the C++ front-end of GCC. Affected packages =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-cpp/gccxml < 0.9.0_pre20090516 >=3D 0.9.0_pre20090516 Description =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D Dmitry E. Oboukhov reported that find_flags in GCC-XML does not handle "/tmp/*.cxx" temporary files securely. Impact =3D=3D=3D=3D=3D=3D A local attacker could perform symlink attacks to overwrite arbitrary files 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 GCC-XML users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose =3Ddev-cpp/gccxml-0.9.0_pre20090516 References =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D [ 1 ] CVE-2008-4957 http://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2008-4957 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-200909-11.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.
