- CWE-682 - Incorrect Calculation
Summary
A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the ssh_kdf() function responsible for key derivation. Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success—the function may mistakenly return a success status even when key derivation fails. This results in uninitialized cryptographic key buffers being used in subsequent communication, potentially compromising SSH sessions' confidentiality, integrity, and availability.

Summary
Polkadot Frontier is an Ethereum and EVM compatibility layer for Polkadot and Substrate. The extrinsic note_min_gas_price_target is an inherent extrinsic, meaning only the block producer can call it. To ensure correctness, the ProvideInherent trait should be implemented for each inherent, which includes the check_inherent call. This allows other nodes to verify if the input (in this case, the target value) is correct. However, prior to commit a754b3d, the check_inherent function has not been implemented for note_min_gas_price_target. This lets the block producer set the target value without verification. The target is then used to set the MinGasPrice, which has an upper and lower bound defined in the on_initialize hook. The block producer can set the target to the upper bound. Which also increases the upper and lower bounds for the next block. Over time, this could result in continuously raising the gas price, making contract execution too expensive and ineffective for users. An attacker could use this flaw to manipulate the gas price, potentially leading to significantly inflated transaction fees. Such manipulation could render contract execution prohibitively expensive for users, effectively resulting in a denial-of-service condition for the network. This is fixed in version a754b3d.

Summary
matrix-sdk-base is the base component to build a Matrix client library. In matrix-sdk-base before 0.14.1, calling the `RoomMember::normalized_power_level()` method can cause a panic if a room member has a power level of `Int::Min`. The issue is fixed in matrix-sdk-base 0.14.1. The affected method isn’t used internally, so avoiding calling `RoomMember::normalized_power_level()` prevents the panic.

"value": "matrix-sdk-base is the base component to build a Matrix client library. In matrix-sdk-base before 0.14.1, calling the `RoomMember::normalized_power_level()` method can cause a panic if a room member has a power level of `Int::Min`. The issue is fixed in matrix-sdk-base 0.14.1. The affected method isn\u2019t used internally, so avoiding calling `RoomMember::normalized_power_level()` prevents the panic."

Mitigation
Phase: Implementation
Description:
- Understand your programming language's underlying representation and how it interacts with numeric calculation. Pay close attention to byte size discrepancies, precision, signed/unsigned distinctions, truncation, conversion and casting between types, "not-a-number" calculations, and how your language handles numbers that are too large or too small for its underlying representation.
Mitigation ID: MIT-8
Phase: Implementation
Strategy: Input Validation
Description:
- Perform input validation on any numeric input by ensuring that it is within the expected range. Enforce that the input meets both the minimum and maximum requirements for the expected range.
Mitigation
Phase: Implementation
Description:
- Use the appropriate type for the desired action. For example, in C/C++, only use unsigned types for values that could never be negative, such as height, width, or other numbers related to quantity.
Mitigation
Phase: Architecture and Design
Strategy: Language Selection
Description:
- Use languages, libraries, or frameworks that make it easier to handle numbers without unexpected consequences.
- Examples include safe integer handling packages such as SafeInt (C++) or IntegerLib (C or C++).
Mitigation
Phase: Architecture and Design
Strategy: Libraries or Frameworks
Description:
- Use languages, libraries, or frameworks that make it easier to handle numbers without unexpected consequences.
- Examples include safe integer handling packages such as SafeInt (C++) or IntegerLib (C or C++).
Mitigation ID: MIT-26
Phase: Implementation
Strategy: Compilation or Build Hardening
Description:
- Examine compiler warnings closely and eliminate problems with potential security implications, such as signed / unsigned mismatch in memory operations, or use of uninitialized variables. Even if the weakness is rarely exploitable, a single failure may lead to the compromise of the entire system.
Mitigation
Phase: Testing
Description:
- Use automated static analysis tools that target this type of weakness. Many modern techniques use data flow analysis to minimize the number of false positives. This is not a perfect solution, since 100% accuracy and coverage are not feasible.
Mitigation
Phase: Testing
Description:
- Use dynamic tools and techniques that interact with the product using large test suites with many diverse inputs, such as fuzz testing (fuzzing), robustness testing, and fault injection. The product's operation may slow down, but it should not become unstable, crash, or generate incorrect results.
CAPEC-128: Integer Attacks
An attacker takes advantage of the structure of integer variables to cause these variables to assume values that are not expected by an application. For example, adding one to the largest positive integer in a signed integer variable results in a negative number. Negative numbers may be illegal in an application and the application may prevent an attacker from providing them directly, but the application may not consider that adding two positive numbers can create a negative number do to the structure of integer storage formats.
CAPEC-129: Pointer Manipulation
This attack pattern involves an adversary manipulating a pointer within a target application resulting in the application accessing an unintended memory location. This can result in the crashing of the application or, for certain pointer values, access to data that would not normally be possible or the execution of arbitrary code. Since pointers are simply integer variables, Integer Attacks may often be used in Pointer Attacks.
