Rsyslog and Sysklogd Integer Overflow Vulnerability Analysis

CVE-2014-3683

What is CVE-2014-3683?

The vulnerability stems from an integer overflow in Rsyslog versions prior to 7.6.7 and 8.x before 8.4.2, as well as Sysklogd version 1.5 and earlier. Attackers can exploit this vulnerability by sending a large priority (PRI) value, which can trigger a denial of service by crashing the affected services. This issue was noted as a consequence of an incomplete fix for a previous vulnerability, highlighting the need for organizations to ensure they are running patched versions of affected software to prevent potential exploitation.
