Debian Security Advisory DSA 052-1 security@debian.org http://www.debian.org/security/ Martin Schulze April 23, 2001


Package : sendfile Vulnerability : broken privileges dropping Problem-Type : local root exploit Debian-specific: no

Daniel Kobras has discovered and fixed a problem in sendfiled which caused the daemon not to drop privileges as expected when sendnig notification mails. Exploiting this a local user can easily make it execute arbitrary code under root privileges.

We recommend that you upgrade your sendfile 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.

Debian GNU/Linux 2.2 alias potato
