Slackware 10.0 / 10.1 / 8.1 / 9.0 / 9.1 / current : dhcpcd DoS (SSA:2005-255-01)

medium Nessus Plugin ID 19864

Synopsis

The remote Slackware host is missing a security update.

Description

New dhcpcd packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, and -current to fix a minor security issue. The dhcpcd daemon can be tricked into reading past the end of the DHCP buffer by a malicious DHCP server, which causes the dhcpcd daemon to crash and results in a denial of service. Of course, a malicious DHCP server could simply give you an IP address that wouldn't work, too, such as 127.0.0.1, but since people have been asking about this issue, here's a fix, and that's the extent of the impact. In other words, very little real impact. Even less detail about this issue may be found in the Common Vulnerabilities and Exposures (CVE) database:
