NetBSD CLCS / EMUXKI Audio Driver Local Denial of Service Vulnerability
Solution: NetBSD has updated this in its current kernel. Users are advised to either obtain and compile the newest kernel for their architecture, or apply the patch to the audio.c file from CVS. From NetBSD advisory 2005-02: The fix for this issue is contained in one file, sys/dev/audio.c The following table lists the fixed revisions and dates of this file for each branch: CVS branch revision date ------------- ----------- ---------------- HEAD 1.196 2005/06/11 netbsd-3 1.192.4.2 2005/06/11 netbsd-2-0 1.182.2.2 2005/06/12 netbsd-2 1.182.2.1.2.2 2005/06/12 netbsd-1-6 1.155.4.7 2005/06/17 The following instructions describe how to upgrade your kernel binaries by updating your source tree and rebuilding and installing a new version of the kernel. In these instructions, replace: BRANCH with the appropriate CVS branch (from the above table) ARCH with your architecture (from uname -m), and KERNCONF with the name of your kernel configuration file. To update from CVS, re-build, and re-install the kernel: # cd src # cvs update -d -P -r BRANCH sys/dev/audio.c # cd sys/arch/ARCH/conf # config KERNCONF # cd ../compile/KERNCONF # make depend;make; make install # reboot |
