The remote host is missing the patch for the advisory SuSE-SA:2004:019 (dhcp/dhcp-server).
The Dynamic Host Configuration Protocol (DHCP) server is used to
configure clients that dynamically connect to a network (WLAN
hotspots, customer networks, ...).
The CERT informed us about a buffer overflow in the logging code of the
server that can be triggered by a malicious client by supplying multiple
hostnames. The hostname strings are concatenated and copied in a
fixed size buffer without checking the buffer bounds.
Other possible buffer overflow conditions exist in using vsprintf()
instead of vsnprintf(). This behavior can be configured during compile-
time. The dhcp/dhcp-server package coming with SUSE LINUX used the
vulnerable vsprintf() function.
Since SuSE Linux 8.1/SuSE Linux Enterprise Server 8 the DHCP server runs
as non-root user in a chroot jail. This setup limits the impact of a
There is no temporary workaround known.
