CVE Catalog

CVE-2006-1624

High
Published: Translated: NVD NIST

Summary

The default configuration of syslogd in the Linux sysklogd package does not enable the -x (disable name lookups) option, allowing remote attackers to cause a denial of service (traffic amplification) via messages with spoofed source IP addresses.

Risk Assessment

The risk involves potential network or system overload due to amplified syslog traffic, which could lead to service unavailability for the organization.

Recommendation

It is recommended to enable the -x option in the syslogd configuration (e.g., in /etc/syslog.conf or by adding -x to the daemon startup line) to disable name lookups and prevent traffic amplification.
