-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3495-1 security@debian.org https://www.debian.org/security/ Sebastien Delafond February 29, 2016 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : xymon CVE ID : CVE-2016-2054 CVE-2016-2055 CVE-2016-2056 CVE-2016-2057 CVE-2016-2058 Markus Krell discovered that xymon, a network- and applications-monitoring system, was vulnerable to the following security issues: CVE-2016-2054 The incorrect handling of user-supplied input in the "config" command can trigger a stack-based buffer overflow, resulting in denial of service (via application crash) or remote code execution. CVE-2016-2055 The incorrect handling of user-supplied input in the "config" command can lead to an information leak by serving sensitive configuration files to a remote user. CVE-2016-2056 The commands handling password management do not properly validate user-supplied input, and are thus vulnerable to shell command injection by a remote user. CVE-2016-2057 Incorrect permissions on an internal queuing system allow a user with a local account on the xymon master server to bypass all network-based access control lists, and thus inject messages directly into xymon. CVE-2016-2058 Incorrect escaping of user-supplied input in status webpages can be used to trigger reflected cross-site scripting attacks. For the stable distribution (jessie), these problems have been fixed in version 4.3.17-6+deb8u1. We recommend that you upgrade your xymon packages.
