FreeBSD Kernel amd64_set_ldt Heap Overflow
Posted Mar 17, 2016
Authored by Core Security Technologies, Francisco Falcon

Core Security Technologies Advisory - An integer signedness error has been found in the amd64_set_ldt() function in the FreeBSD kernel code (define d in the /sys/amd64/amd64/sys_machdep.c file), which implements the i386_set_ldt system call on the amd64 version of the OS. This integer signedness issue ultimately leads to a heap overflow in the kernel, allowing local unprivileged attackers to crash the system. FreeBSD 10.2 amd64 is affected.

Microsoft Windows Media Center Incorrectly Resolved Reference
Posted Dec 9, 2015
Authored by Core Security Technologies, Francisco Falcon

Core Security Technologies Advisory - The 'application' tag in Microsoft Windows Media Center link files (.mcl extension) can include a 'run' parameter, which indicates the path of a file to be launched when opening the MCL file, or a 'url' parameter, which indicates the URL of a web page to be loaded within the Media Center's embedded web browser. A specially crafted MCL file having said 'url' parameter pointing to the MCL file itself can trick Windows Media Center into rendering the very same MCL file as a local HTML file within the Media Center's embedded web browser.

FreeBSD Security Advisory - Kernel Memory Disclosure / Corruption
Posted Jan 28, 2015
Authored by Francisco Falcon, Clement LECIGNE | Site security.freebsd.org

FreeBSD Security Advisory - SCTP protocol provides reliable, flow-controlled, two-way transmission of data. It is a message oriented protocol and can support the SOCK_STREAM and SOCK_SEQPACKET abstractions. SCTP allows the user to choose between multiple scheduling algorithms to optimize the sending behavior of SCTP in scenarios with different requirements. Due to insufficient validation of the SCTP stream ID, which serves as an array index, a local unprivileged attacker can read or write 16-bits of kernel memory.

FreeBSD Kernel Crash / Code Execution / Disclosure
Posted Jan 28, 2015
Authored by Core Security Technologies, Francisco Falcon | Site coresecurity.com

Core Security Technologies Advisory - Multiple vulnerabilities have been found in the FreeBSD kernel code that implements the vt console driver (previously known as Newcons) and the code that implements SCTP sockets. These vulnerabilities could allow local unprivileged attackers to disclose kernel memory containing sensitive information, crash the system, and execute arbitrary code with superuser privileges.

VirtualBox 3D Acceleration Virtual Machine Escape
Posted Aug 14, 2014
Authored by Francisco Falcon, juan vazquez, Florian Ledoux | Site metasploit.com

This Metasploit module exploits a vulnerability in the 3D Acceleration support for VirtualBox. The vulnerability exists in the remote rendering of OpenGL-based 3D graphics. By sending a sequence of specially crafted of rendering messages, a virtual machine can exploit an out of bounds array access to corrupt memory and escape to the host. This Metasploit module has been tested successfully on Windows 7 SP1 (64 bits) as Host running Virtual Box 4.3.6.

SAP Netweaver Message Server Buffer Overflow
Posted Feb 15, 2013
Authored by Core Security Technologies, Francisco Falcon, Martin Gallo | Site coresecurity.com

Core Security Technologies Advisory - Multiple vulnerabilities have been found in SAP Netweaver that could allow an unauthenticated remote attacker to execute arbitrary code and lead to denial of service conditions. The vulnerabilities are triggered sending specially crafted SAP Message Server packets to remote TCP ports 36NN and/or 39NN (being NN the SAP system number) of a host running the 'Message Server' service, part of SAP Netweaver Application Server ABAP. By sending different messages, the different vulnerabilities can be triggered.

Foxit Reader 3.0 Open Execute Action Stack Based Buffer Overflow
Posted May 22, 2012
Authored by bannedit, Francisco Falcon | Site metasploit.com

This Metasploit module exploits a buffer overflow in Foxit Reader 3.0 builds 1301 and earlier. Due to the way Foxit Reader handles the input from an "Launch" action, it is possible to cause a stack-based buffer overflow, allowing an attacker to gain arbitrary code execution under the context of the user.

Core Security Technologies Advisory - The Administration Console of Oracle GlassFish Server, which is listening by default on port 4848/TCP, is prone to an authentication bypass vulnerability. This vulnerability can be exploited by remote attackers to access sensitive data on the server without being authenticated, by making 'TRACE' requests against the Administration Console. Oracle GlassFish Server version 3.0.1 and Sun GlassFish Enterprise Server version 2.1.1 are affected.

Core Security Technologies Advisory 2009.1126
Posted Feb 2, 2010
Authored by Core Security Technologies, Francisco Falcon | Site coresecurity.com

Core Security Technologies Advisory - Corel Paint Shop Pro Photo X2 is prone to a heap-based buffer overflow when processing malformed FPX files, because it trusts user-controlled data located inside a FPX file and uses it as a loop counter when copying data from a FPX file into a fixed-size buffer located in the heap. This vulnerability can be exploited to overwrite adjacent heap chunks metadata, and possibly to gain arbitrary code execution.
