Title
Ledger Bitcoin App 2.1.0 Address Derivation Error via Miniscript
Summary
Ledger Bitcoin app versions 2.1.0 and 2.1.1 contain an address derivation vulnerability that allows attackers to cause incorrect Bitcoin addresses to be displayed by exploiting improper handling of miniscript policies containing the a: fragment. Attackers can craft malicious miniscript policies that cause the device to derive and display incorrect receiving addresses, potentially leading to funds being sent to unintended addresses.

Title
Ledger Nano X, Flex, Stax MCU Firmware Update Denial of Service
Summary
Ledger Nano X, Flex, and Stax devices contain a denial of service vulnerability in the MCU firmware update process due to missing validation of the reset_handler parameter during firmware flashing. An attacker can provide a crafted reset_handler address pointing to invalid memory or attacker-controlled code to cause the device to enter an unrecoverable fault state during boot, resulting in permanent loss of operability.

Title
Ledger Live hw-app-eth EIP-712 Message Parsing Integer Truncation
Summary
Ledger Live with vulnerable versions of ledgerhq/hw-app-eth prior to 6.34.7 contains an integer parsing vulnerability that allows attackers to manipulate EIP-712 typed data messages by exploiting incorrect hexadecimal field parsing when values contain an odd number of characters. Attackers can obtain signatures on truncated or misinterpreted message values to authorize unintended blockchain transactions, such as asset transfers at incorrect amounts.

Summary
Ledger Live before 2.7.0 does not handle Bitcoin's Replace-By-Fee (RBF). It increases the user's balance with the value of an unconfirmed transaction as soon as it is received (before the transaction is confirmed) and does not decrease the balance when it is canceled. As a result, users are exposed to basic double spending attacks, amplified double spending attacks, and DoS attacks without user consent.
Severity
No CVSS data available.

Title
Ledger Bitcoin App 2.1.0 Address Derivation Error via Miniscript
Summary
Ledger Bitcoin app versions 2.1.0 and 2.1.1 contain an address derivation vulnerability that allows attackers to cause incorrect Bitcoin addresses to be displayed by exploiting improper handling of miniscript policies containing the a: fragment. Attackers can craft malicious miniscript policies that cause the device to derive and display incorrect receiving addresses, potentially leading to funds being sent to unintended addresses.

Title
Ledger Live hw-app-eth EIP-712 Message Parsing Integer Truncation
Summary
Ledger Live with vulnerable versions of ledgerhq/hw-app-eth prior to 6.34.7 contains an integer parsing vulnerability that allows attackers to manipulate EIP-712 typed data messages by exploiting incorrect hexadecimal field parsing when values contain an odd number of characters. Attackers can obtain signatures on truncated or misinterpreted message values to authorize unintended blockchain transactions, such as asset transfers at incorrect amounts.

Title
Ledger Nano X, Flex, Stax MCU Firmware Update Denial of Service
Summary
Ledger Nano X, Flex, and Stax devices contain a denial of service vulnerability in the MCU firmware update process due to missing validation of the reset_handler parameter during firmware flashing. An attacker can provide a crafted reset_handler address pointing to invalid memory or attacker-controlled code to cause the device to enter an unrecoverable fault state during boot, resulting in permanent loss of operability.

Summary
Ledger Live before 2.7.0 does not handle Bitcoin's Replace-By-Fee (RBF). It increases the user's balance with the value of an unconfirmed transaction as soon as it is received (before the transaction is confirmed) and does not decrease the balance when it is canceled. As a result, users are exposed to basic double spending attacks, amplified double spending attacks, and DoS attacks without user consent.

VAR-201908-0921
Vulnerability from variot - Updated: 2023-12-18 13:43On Ledger Nano S and Nano X devices, a side channel for the row-based OLED display was found. The power consumption of each row-based display cycle depends on the number of illuminated pixels, allowing a partial recovery of display contents. For example, a hardware implant in the USB cable might be able to leverage this behavior to recover confidential secrets such as the PIN and BIP39 mnemonic. In other words, the side channel is relevant only if the attacker has enough control over the device's USB connection to make power-consumption measurements at a time when secret data is displayed. The side channel is not relevant in other circumstances, such as a stolen device that is not currently displaying secret data. Unauthorized attackers can exploit the vulnerability to obtain sensitive information about affected components. This vulnerability stems from configuration errors in network systems or products during operation

"data": "On Ledger Nano S and Nano X devices, a side channel for the row-based OLED display was found. The power consumption of each row-based display cycle depends on the number of illuminated pixels, allowing a partial recovery of display contents. For example, a hardware implant in the USB cable might be able to leverage this behavior to recover confidential secrets such as the PIN and BIP39 mnemonic. In other words, the side channel is relevant only if the attacker has enough control over the device\u0027s USB connection to make power-consumption measurements at a time when secret data is displayed. The side channel is not relevant in other circumstances, such as a stolen device that is not currently displaying secret data. Unauthorized attackers can exploit the vulnerability to obtain sensitive information about affected components. This vulnerability stems from configuration errors in network systems or products during operation",
