For completeness below is the original advisory: Paul Starzetz discovered a flaw in bounds checking in mremap() in the Linux kernel (present in version 2.4.x and 2.6.x) which may allow a local attacker to gain root privileges. Version 2.2 is not affected by this bug. For the stable distribution (woody) this problem has been fixed in version 2.4.18-13 for the alpha architecture. For the unstable distribution (sid) this problem will be fixed soon with newly uploaded packages. We recommend that you upgrade your kernel packages. This problem has been fixed in the upstream version 2.4.24 as well. 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.
