The new version includes fixes from DSA 146-1. For completness we enclose the text of the other advisory: An integer overflow bug has been discovered in the RPC library used by dietlibc, a libc optimized for small size, which is derived from the SunRPC library. This bug could be exploited to gain unauthorized root access to software linking to this code. The packages below also fix integer overflows in the calloc, fread and fwrite code. They are also more strict regarding hostile DNS packets that could lead to a vulnerability otherwise. This problem has been fixed in version 0.12-2.4 for the current stable distribution (woody) and in version 0.20-0cvs20020808 for the unstable distribution (sid). Debian 2.2 (potato) is not affected since it doesn't contain dietlibc packages. We recommend that you upgrade your dietlibc packages immediately. 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.
