Title
Ashlar-Vellum Cobalt, Xenon, Argon, Lithium Heap-based Buffer Overflow
Summary
In Ashlar-Vellum Cobalt versions prior to v12 SP2 Build (1204.200), the affected application lacks proper validation of user-supplied data when parsing CO files. This could lead to a heap-based buffer overflow. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.

Title
Another heap overflow in push_back_helper
Summary
eprosima Fast DDS is a C++ implementation of the Data Distribution Service standard of the Object Management Group. Prior to versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6, even after the fix at commit 3492270, malformed `PID_PROPERTY_LIST` parameters cause heap overflow at a different program counter. This can remotely crash any Fast-DDS process. Versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6 contain a patch for this issue.

Title
Heap overflow in push_back_helper due to a CDR message
Summary
eprosima Fast DDS is a C++ implementation of the Data Distribution Service standard of the Object Management Group. Prior to versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6, heap can be overflowed by providing a PID_PROPERTY_LIST parameter that contains a CDR string with length larger than the size of actual content. In `eprosima::fastdds::dds::ParameterPropertyList_t::push_back_helper`, `memcpy` is called to first copy the octet'ized length and then to copy the data into `properties_.data`. At the second memcpy, both `data` and `size` can be controlled by anyone that sends the CDR string to the discovery multicast port. This can remotely crash any Fast-DDS process. Versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6 contain a patch for this issue.

Title
PDF-XChange Editor OXPS File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
Summary
PDF-XChange Editor OXPS File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of PDF-XChange Editor. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of OXPS files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-19655.

Title
PDF-XChange Editor PDF File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
Summary
PDF-XChange Editor PDF File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of PDF-XChange Editor. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of PDF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-19640.

Mitigation
Pre-design: Use a language or compiler that performs automatic bounds checking.
Mitigation
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation MIT-10
Operation
Build and Compilation
Strategy: Environment Hardening
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking.
- D3-SFCV (Stack Frame Canary Validation) from D3FEND [REF-1334] discusses canary-based detection in detail.
Mitigation MIT-11
Operation
Build and Compilation
Strategy: Environment Hardening
- Run or compile the software using features or extensions that randomly arrange the positions of a program's executable and libraries in memory. Because this makes the addresses unpredictable, it can prevent an attacker from reliably jumping to exploitable code.
- Examples include Address Space Layout Randomization (ASLR) [REF-58] [REF-60] and Position-Independent Executables (PIE) [REF-64]. Imported modules may be similarly realigned if their default memory addresses conflict with other modules, in a process known as "rebasing" (for Windows) and "prelinking" (for Linux) [REF-1332] using randomly generated addresses. ASLR for libraries cannot be used in conjunction with prelink since it would require relocating the libraries at run-time, defeating the whole purpose of prelinking.
- For more information on these techniques see D3-SAOR (Segment Address Offset Randomization) from D3FEND [REF-1335].
Mitigation
Implementation
Implement and perform bounds checking on input.
Mitigation
Implementation
Strategy: Libraries or Frameworks
Do not use dangerous functions such as gets. Look for their safe equivalent, which checks for the boundary.
Mitigation
Operation
Use OS-level preventative functionality. This is not a complete solution, but it provides some defense in depth.
CAPEC-92: Forced Integer Overflow
This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
