Red Hat Security Advisory 2015-1194-01 – PostgreSQL is an advanced object-relational database management system. A double-free flaw was found in the connection handling. An unauthenticated attacker could exploit this flaw to crash the PostgreSQL back end by disconnecting at approximately the same time as the authentication time out is triggered. It was discovered that PostgreSQL did not properly check the return values of certain standard library functions. If the system is in a state that would cause the standard library functions to fail, for example memory exhaustion, an authenticated user could exploit this flaw to disclose partial memory contents or cause the GSSAPI authentication to use an incorrect keytab file.

Red Hat Security Advisory 2015-1193-01 – Xerces-C is a validating XML parser written in a portable subset of C++. A flaw was found in the way the Xerces-C XML parser processed certain XML documents. A remote attacker could provide specially crafted XML input that, when parsed by an application using Xerces-C, would cause that application to crash. All xerces-c users are advised to upgrade to this updated package, which contains a backported patch to correct this issue.

Ubuntu Security Notice 2657-1 – It was discovered that unattended-upgrades incorrectly performed authentication checks in certain configurations. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to install altered packages.

Debian Linux Security Advisory 3297-1 – It was discovered that unattended-upgrades, a script for automatic installation of security upgrades, did not properly authenticate downloaded packages when the force-confold or force-confnew dpkg options were enabled via the DPkg::Options::* apt configuration.

The Watchguard XCS virtual appliance contains a number of vulnerabilities, including unauthenticated SQL injection, command execution and privilege escalation. By combining these vulnerabilities, an attacker may remotely obtain root privileges on the underlying host. Versions 10.0 and below are affected.

The CollabNet Subversion Edge Management Frontend fails to implement any cross site request forgery protection. Fixed in version 5.0. Version 4.0.11 is affected.

Wedge Networks WedgeOS Virtual Appliance contains a number of security vulnerabilities, including unauthenticated arbitrary file read as root, command injection in the web interface, privilege escalation to root, and command execution via the system update functionality. Versions 4.0.4 and below are affected.

The CollabNet Subversion Edge Management Frontend allows authenticated admins to read arbitrary local files via logfile “filename” parameter of the tail action. Fixed in version 5.0. Version 4.0.11 is affected.
