REDHAT-BUG-1066578: Buffer Overflow
First published: Tue Feb 18 2014(Updated: )
A potential buffer overflow vulnerability was reported in Icinga [1],[2] which could possibly be exploited by remote attackers to cause a denial of service. This vulnerability is caused due to a boundary error in the cmd_submitf() function. This code in Icinga originated in Nagios, and a visual inspection of the code indicates Nagios is likewise affected. <a href="https://access.redhat.com/security/cve/CVE-2014-1878">CVE-2014-1878</a> was assigned to Icinga, however given that the code is identical and has the same origin (Nagios is the originator) the same CVE should also apply to Nagios. This is fixed in Icinga git [3].
