Off-by-one error in the processcgivars function in contrib/daemonchk.c in Nagios Core 3.5.1, 4.0.2, and earlier allows remote authenticated users to obtain sensitive information from process memory or cause a denial of service (crash) via a long string in the last key value in the variable list, which triggers a heap-based buffer over-read.

Multiple off-by-one errors in Nagios Core 3.5.1, 4.0.2, and earlier, and Icinga before 1.8.5, 1.9 before 1.9.4, and 1.10 before 1.10.2 allow remote authenticated users to obtain sensitive information from process memory or cause a denial of service (crash) via a long string in the last key value in the variable list to the processcgivars function in (1) avail.c, (2) cmd.c, (3) config.c, (4) extinfo.c, (5) histogram.c, (6) notifications.c, (7) outages.c, (8) status.c, (9) statusmap.c, (10) summary.c, and (11) trends.c in cgi/, which triggers a heap-based buffer over-read.

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 cmdsubmitf() function. This code in Icinga originated in Nagios, and a visual inspection of the code indicates Nagios is likewise affected.

CVE-2014-1878 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].
