MDKSA-2003:007 - Updated dhcp packages fix remote code execution vulnerability

by Nikola Strahija on January 22nd, 2003 Several potential vulnerabilities were detected by the ISC (Internet Software Consortium) in their dhcp server software. The vulnerabilities affect the minires library and may be exploitable as stack buffer overflows, which could lead to remote code execution. All Mandrake Linux users are encouraged to upgrade; only Mandrake Linux 8.0 came with dhcp 2.x and is not vulnerable.

To upgrade automatically, use MandrakeUpdate. The verification of md5
checksums and GPG signatures is performed automatically for you.

If you want to upgrade manually, download the updated package from one
of our FTP server mirrors and upgrade with "rpm -Fvh *.rpm". A list of
FTP mirrors can be obtained from:

http://www.mandrakesecure.net/en/ftp.php

Please verify the update prior to upgrading to ensure the integrity of
the downloaded package. You can do this with the command:

rpm --checksig

All packages are signed by MandrakeSoft for security. You can obtain
the GPG public key of the Mandrake Linux Security Team from:

https://www.mandrakesecure.net/RPM-GPG-KEYS

Please be aware that sometimes it takes the mirrors a few hours to
update.
