CVE-2025-49600
A flaw was found in mbedtls. The mbedtlslmsverify function may accept forged Leighton-Micali signatures when hash computation fails and internal error conditions are not properly checked. This flaw allows an attacker with physical access to create invalid signatures. This issue occurs because...
Missing Cryptographic Step
Overview Affected versions of this package are vulnerable to Missing Cryptographic Step in the mbedtlslmsverify process when internal errors from the createmerkleleafvalue and createmerkleinternalvalue functions are not checked. An attacker can cause the acceptance of invalid signatures by induci...
CVE-2025-49600
In MBedTLS, CVE-2025-49600 affects 3.3.0 to before 3.6.4, where mbedtls_lms_verify can accept forged Leighton-Micali Signatures in fault scenarios. The root cause is unchecked return values from internal Merkle-tree calls (create_merkle_leaf_value and create_merkle_internal_value) which can leave...
CVE-2025-49600
In MbedTLS 3.3.0 before 3.6.4, mbedtlslmsverify may accept invalid signatures if hash computation fails and internal errors go unchecked, enabling LMS Leighton-Micali Signature forgery in a fault scenario. Specifically, unchecked return values in mbedtlslmsverify allow an attacker who can induce ...
Improper Input Validation
tiny-secp256k1 is vulnerable to improper input validation. The vulnerability is due to the ability to pass a malicious JSON-stringifiable object to the verify function when the global Buffer is overridden by the NPM buffer package, which allows an attacker to perform a type confusion attack and...
Windows Defender Application Control Bypass
The vulnerability of Windows Defender Application Control WDAC on Windows operating systems is related to errors in verifying the cryptographic signature. Exploiting this vulnerability can allow a hacker to circumvent existing security restrictions...
CVE-2023-28904
A logic flaw leading to a RAM buffer overflow in the bootloader component of the MIB3 infotainment unit allows an attacker with physical access to the MIB3 ECU to bypass firmware signature verification and run arbitrary code in the infotainment system at boot process...
PT-2025-28012
Name of the Vulnerable Software and Affected Versions: MbedTLS versions 3.3.0 through 3.6.3 Description: The issue allows an attacker to bypass LMS signature verification by reusing stale stack data, resulting in the acceptance of an invalid signature. This occurs when unchecked return values in...
