Red Hat Security Advisory 2015-1642-03 – Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector, JBoss HTTP Connector, Hibernate, and the Tomcat Native library. A flaw was found in the way the mod_cluster manager processed certain MCMP messages. An attacker with access to the network from which MCMP messages are allowed to be sent could use this flaw to execute arbitrary JavaScript code in the mod_cluster manager web interface.

Red Hat Security Advisory 2015-1643-01 – The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that the Linux kernel’s ping socket implementation did not properly handle socket unhashing during spurious disconnects, which could lead to a use-after-free flaw. On x86-64 architecture systems, a local user able to create ping sockets could use this flaw to crash the system. On non-x86-64 architecture systems, a local user able to create ping sockets could use this flaw to escalate their privileges on the system.

Red Hat Security Advisory 2015-1636-01 – The net-snmp packages provide various libraries and tools for the Simple Network Management Protocol, including an SNMP library, an extensible agent, tools for requesting or setting information from SNMP agents, tools for generating and handling SNMP traps, a version of the netstat command which uses SNMP, and a Tk/Perl Management Information Base browser. It was discovered that the snmp_pdu_parse() function could leave incompletely parsed varBind variables in the list of variables. A remote, unauthenticated attacker could use this flaw to crash snmpd or, potentially, execute arbitrary code on the system with the privileges of the user running snmpd.

Debian Linux Security Advisory 3336-1 – Several vulnerabilities have been discovered in nss, the Mozilla Network Security Service library.

Ubuntu Security Notice 2710-2 – USN-2710-1 fixed vulnerabilities in OpenSSH. The upstream fix for CVE-2015-5600 caused a regression resulting in random authentication failures in non-default configurations. This update fixes the problem.

Debian Linux Security Advisory 3337-1 – Gustavo Grieco discovered a heap overflow in the processing of BMP images which may result in the execution of arbitrary code if a malformed image is opened.

Ubuntu Security Notice 2719-1 – Marcelo Ricardo Leitner discovered a race condition in the Linux kernel’s SCTP address configuration lists when using Address Configuration Change (ASCONF) options on a socket. An unprivileged local user could exploit this flaw to cause a denial of service (system crash).

Debian Linux Security Advisory 3325-2 – The security update from DSA-3325-1 caused a regression for the oldstable distribution (wheezy). In some configurations, apache2 would fail to start with a spurious error message about the certificate chain. This update fixes this problem.
