Vulnerability Assessment Details

MDKSA-2004:061: dhcp

Vulnerability Assessment Summary
Check for the version of the dhcp package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory MDKSA-2004:061 (dhcp).


A vulnerability in how ISC's DHCPD handles syslog messages can permit a malicious
attacker with the ability to send special packets to the DHCPD listening port to
crash the daemon, causing a Denial of Service. It is also possible that they may
be able to execute arbitrary code on the vulnerable server with the permissions
of the user running DHCPD, which is usually root.
A similar vulnerability also exists in the way ISC's DHCPD makes use of the
vsnprintf() function on system that do not support vsnprintf(). This
vulnerability could also be used to execute arbitrary code and/or perform a DoS
attack. The vsnprintf() statements that have this problem are defined after the
vulnerable code noted above, which would trigger the previous problem rather
than this one.
Thanks to Gregory Duchemin and Solar Designer for discovering these flaws.
The updated packages contain 3.0.1rc14 which is not vulnerable to these
problems. Only ISC DHCPD 3.0.1rc12 and 3.0.1rc13 are vulnerable to these issues.
