NetBSD does not run a CVS server in the default install. Relatively few users have reason to configure one, and only those who do are affected. Technical Details ================= http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0396 Solutions and Workarounds ========================= If you run a CVS server: We highly recommend you to upgrade your cvs binary to 1.11.16, or 1.12.8 or higher. The following instructions describe how to upgrade your cvs binaries by updating your source tree and rebuilding and installing a new version of cvs. * NetBSD-current: Systems running NetBSD-current dated from before 2004-05-21 should be upgraded to NetBSD-current dated 2004-05-22 or later. The following directories need to be updated from the netbsd-current CVS branch (aka HEAD): gnu/dist/cvs gnu/usr.bin/cvs To update from CVS, re-build, and re-install cvs: # cd src # cvs update -d -P gnu/dist/cvs gnu/usr.bin/cvs # cd gnu/usr.bin/cvs # make USETOOLS=no cleandir dependall # make USETOOLS=no install * NetBSD 1.6, 1.6.1, 1.6.2: The binary distribution of NetBSD 1.6, 1.6.1 and 1.6.2 are vulnerable. Systems running NetBSD 1.6 sources dated from before 2004-06-01 should be upgraded from NetBSD 1.6 sources dated 2004-06-02 or later. Alternately, delete your cvs binaries, and update from pkgsrc. NetBSD 1.6.3 will include the fix. The following directories need to be updated from the netbsd-1-6 CVS branch: gnu/dist/cvs gnu/usr.bin/cvs To update from CVS, re-build, and re-install cvs: # cd src # cvs update -d -P -r netbsd-1-6 gnu/dist/cvs gnu/usr.bin/cvs # cd gnu/usr.bin/cvs # make USETOOLS=no cleandir dependall # make USETOOLS=no install * pkgsrc: If your system has devel/cvs pkgsrc version 1.11.15 or lower, update to 1.11.16 Thanks To ========= Matthias Scheler and Curt Sampson Revision History ================ 2004-06-03 Initial release More Information ================ Advisories may be updated as new information becomes available.
