Debian alert: New dhcpcd packages fix remote command execution vulnerability
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 219-1 security@debian.org http://www.debian.org/security/ Martin Schulze December 31st, 2002 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : dhcpcd Vulnerability : remote command execution Problem-Type : remote Debian-specific: no BugTraq Id : 6200 Simon Kelly discovered a vulnerability in dhcpcd, an RFC2131 and RFC1541 compliant DHCP client daemon, that runs with root privileges on client machines. A malicious administrator of the regular or an untrusted DHCP server may execute any command with root privileges on the DHCP client machine by sending the command enclosed in shell metacharacters in one of the options provided by the DHCP server. This problem has been fixed in version 1.3.17pl2-8.1 for the old stable distribution (potato) and in version 1.3.22pl2-2 for the testing (sarge) and unstable (sid) distributions. The current stable distribution (woody) does not contain a dhcpcd package. We recommend that you upgrade your dhcpcd package (on the client machine). 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.
