Debian DLA-1615-1 : nagios3 security update
High Nessus Plugin ID 119875
SynopsisThe remote Debian host is missing a security update.
DescriptionSeveral issues were corrected in nagios3, a monitoring and management system for hosts, services and networks.
It was discovered that local users with access to an account in the nagios group are able to gain root privileges via a symlink attack on the debug log file.
An issue was corrected that allowed remote attackers to cause a stack-based buffer overflow and subsequently a denial of service (segmentation fault) via a long message to cmd.cgi.
CVE-2013-7205 | CVE-2013-7108
A flaw was corrected in Nagios that could be exploited to cause a denial of service. This vulnerability is induced due to an off-by-one error within the process_cgivars() function, which can be exploited to cause an out-of-bounds read by sending a specially crafted key value to the Nagios web UI.
For Debian 8 'Jessie', these problems have been fixed in version 3.5.1.dfsg-2+deb8u1.
We recommend that you upgrade your nagios3 packages.
