Last modified

CVE-2011-3200 is a vulnerability of currently unknown severity. Stack-based buffer overflow in the parseLegacySyslogMsg function in tools/syslogd.c in rsyslogd in rsyslog 4.6.x before 4.6.8 and 5.2.0 through 5.8.4 might allow remote attackers to cause a denial of service (application exit) via a long TAG in a legacy syslog message.. EPSS estimates a 20.76% chance of exploitation in the next 30 days.
