This hole allows local users to obtain root privileges by using ptrace to attach to a child process that is spawned by the kernel. Remote exploitation of this hole is not possible. This advisory only covers kernel packages for the big and little endian MIPS architectures. Other architectures will be covered by separate advisories. For the stable distribution (woody) this problem has been fixed in version 2.4.17-0.020226.2.woody1 of kernel-patch-2.4.17-mips (mips+mipsel) and in version 2.4.19-0.020911.1.woody1 of kernel-patch-2.4.19-mips (mips only). The old stable distribution (potato) is not affected by this problem for these architectures since mips and mipsel were first released with Debian GNU/Linux 3.0 (woody). For the unstable distribution (sid) this problem has been fixed in version 2.4.19-0.020911.6 of kernel-patch-2.4.19-mips (mips+mipsel). We recommend that you upgrade your kernel-images packages immediately. Upgrade Instructions - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.
