CVE-2006-1624
The default configuration of syslogd in the Linux sysklogd package does not enable the -x (disable name lookups) option, which allows remote attackers to cause a denial of service (traffic amplification) via messages with spoofed source IP addresses.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.85%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
