CVE-2011-3200 describes a stack-based buffer overflow in the parseLegacySyslogMsg function of rsyslogd, affecting versions 4.6.x before 4.6.8 and 5.2.0 through 5.8.4. This vulnerability allows remote attackers to cause a denial of service by sending a crafted legacy syslog message with an excessively long TAG. With a CVSS score of 5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P), it is remotely exploitable with low attack complexity, leading to application exit. While not listed in CISA's KEV catalog, a Metasploit module exists for this DoS vulnerability, though there is minimal community discussion or media coverage.
