iDefense Security Advisory 12.11.07 - Remote exploitation of a heap corruption vulnerability in Microsoft Corp.'s Internet Explorer web browser allows attackers to execute arbitrary code in the context of the current user. The vulnerability lies in the JavaScript setExpression method, which is implemented in mshtml.dll. When malformed parameters are supplied, memory can be corrupted in a way that results in Internet Explorer accessing a previously deleted object. By creating a specially crafted web page, it is possible for an attacker to control the contents of the memory pointed to by the released object. This allows an attacker to execute arbitrary code. As of April 5th, 2007, iDefense testing shows that Internet Explorer 6.0 and Internet Explorer 7.0 with all available security patches are vulnerable. Older versions of Internet Explorer may also be vulnerable.

When executing a setuid-root binary, the Mach kernel does not reset the current thread Mach port, or the current thread Mach Exception Port. By first creating and obtaining write access to a Mach port, and then executing a set-uid root binary, an attacker can write arbitrary data into the address space of the process running as root. This leads to arbitrary code execution in the privileged process.

The vulnerability exists within a function responsible for allocating an mbuf. mbufs are a BSD concept, long used by BSD kernels to allocate buffers for storing network related data. iDefense has confirmed the existence of this vulnerability in Mac OS X 10.4.10, Workstation and Server editions. Previous versions may also be affected.

The vulnerability exists within the function responsible for adding an AppleTalk zone to an interface's routing table. A zone can be thought of as something similar to a Windows Domain. iDefense has confirmed the existence of this vulnerability in Mac OS X 10.4.10, Workstation and Server editions. Previous versions may also be affected.
36fda99fdbd5125a1d1b3bffbc10bbe5bf332f6cbb674f55ea2665d857cc06dbiDefense Security Advisory 11.14.07 - Local exploitation of a heap based buffer overflow in Apple Inc.'s OS X may allow an attacker to execute arbitrary code in kernel context. The vulnerability exists within a function responsible for sending an ASP (AppleTalk Session Protocol) message on an AppleTalk socket. When allocating a buffer, the kernel uses a user provided integer to perform an arithmetic operation that calculates the number of bytes to allocate. This calculation can overflow, leading to the allocation of a buffer of insufficient size. This results in an exploitable heap based buffer overflow within the kernel. iDefense has confirmed the existence of this vulnerability in Mac OS X 10.4.10, Workstation and Server editions. Previous versions may also be affected.

The problem specifically exists within the bpf_filter_init function. In several places throughout this function, values supplied from a potential attacker are used as array indexes without proper bounds checking. By making IOCTL requests with specially chosen values, attackers are able to corrupt the stack, or pool memory, within the kernel. iDefense has confirmed the existence of this vulnerability in version 4.0.1 of WinPcap as included in Wireshark 0.99.6a. The version of NPF.SYS tested was 4.0.0.901. iDefense suspects older versions to also be vulnerable.

This vulnerability exists due to insufficient checking for directory traversal sequences when processing the DBLANG environment variable. By using values containing directory traversal specifiers, such as "../", an attacker can cause set-uid binaries to use Native Language Support (NLS) message files under their control. iDefense confirmed the existence of this vulnerability in IBM Corp.'s Informix Dynamic Server version 10.00 UC6TL installed on a Linux system. Other versions are also suspected as vulnerable. Versions for other supported Unix systems should also be considered vulnerable.

Several methods within the vulnerable ActiveX control (CLSID B49C4597-8721-4789-9250-315DFBD9F525) were found to be vulnerable to stack-based buffer overflows. In each case, variable length attacker supplied data is copied into a fixed-size stack buffer using the strcpy() function. Since no input validation is performed, it is possible to corrupt stack memory, resulting in an exploitable condition. iDefense has confirmed the existence of this vulnerability in version 2.6.1.11 of America Online's AmpX.dll. Other versions are suspected to be vulnerable.

As part of its design, DebugView loads a kernel module Dbgv.sys. This module includes functionality that can be abused to copy user supplied data into the kernel, to controlled addresses. This allows malicious users to inject arbitrary code into the running kernel. iDefense confirmed the existence of this vulnerability in Microsoft DebugView version 4.64. The specific file version of Dbgv.sys is 4.60.0.0. This file is deleted automatically after being loaded and will not be found on disk. Previous versions are suspected to be vulnerable as well.

The problem specifically exists within sendrmt function. This function is called when a user tries to send mail using the "m" command. Within this function, several sprintf calls are made to concatenate user-supplied input with static strings. No bounds checking is performed to ensure that the resulting string will fit in the destination buffer located on the stack. By supplying a long parameter, an attacker is able to overwrite program control data located on the stack and take control of the affected process. iDefense has confirmed the existence of this vulnerability within AIX version 5.3 (5300-06) and 5.2. Previous versions are suspected to be vulnerable.

The problem specifically exists within the domacro() function. This function is called when executing a macro via the '$' command within the ftp program. When executing a macro, the parameter is copied to a fixed size stack buffer using an unbounded call to strcpy(). By specifying a long argument, an attacker is able to overwrite program control data located on the stack and take control of the affected process. iDefense has confirmed the existence of this vulnerability in AIX version 5.3 (5300-06). Previous versions are suspected to be vulnerable.

The vulnerability exists within the parsing of the '-V' command line option. The argument to this option is copied into a fixed size stack buffer using the sprintf() function without properly validating the length. This leads to an exploitable stack buffer overflow. iDefense has confirmed the existence of this vulnerability in AIX version 5.2 and 5.3. Previous versions may also be affected.

The problem specifically exists within dns_name_fromtext function within the libdns.a library. This function is called when processing the '-y' command line parameter to the dig program. By supplying a specially crafted TSIG key parameter, an attacker is able to cause an integer underflow, resulting in potentially exploitable heap corruption. iDefense has confirmed the existence of this vulnerability within AIX version 5.2. Previous versions are suspected to be vulnerable. AIX 5.3 is not vulnerable since the dig command is no longer installed set-uid root.

The problem specifically exists within the main function. While processing command line arguments, the crontab program will copy a user-supplied argument to a fixed size BSS (data segment) buffer. Since no bounds checking is performed, it's possible to overwrite a large portion of the data stored in the BSS memory area. iDefense has confirmed the existence of this vulnerability within AIX version 5.2. Previous versions are suspected to be vulnerable. AIX 5.3 does not appear to be vulnerable.
bf2bf7ab5d98550fc89a5faddb98bd4109429208cc010b3c2097a31ab31c0e91iDefense Security Advisory 10.30.07 - Local exploitation of a file access vulnerability in the swcons command included in multiple versions of IBM Corp.'s AIX could allow for the creation or modification of arbitrary files anywhere on the system. The vulnerability specifically exists due to a lack of sanity checking when using the -p option. If a user specifies a file with the -p option, the contents of that file will be overwritten with 65,535 bytes of uncontrolled data. If the file doesn't exist, it will be created. In both cases, the file will also be converted to mode 222, which allows all users on the system to modify it. By specifying a system file, users can cause a denial of service condition or elevate privileges. iDefense has confirmed the existence of this vulnerability on IBM AIX version 5.2. It is suspected that previous versions are also vulnerable.
