The weakness could enable a denial of service (crash) or potentially the execution of arbitrary code if a vulnerable version of cpio is used to extract or to list the contents of a maliciously crafted archive. For the stable distribution (etch), these problems have been fixed in version 2.6-18.1+etch1. For the unstable distribution (sid), these problems have been fixed in version 2.9-5. We recommend that you upgrade your cpio packages. Upgrade instructions - - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
