Use of a Broken or Risky Cryptographic Algorithm in the function mbedtls mpi exp mod in lignum.c in Mbed TLS Mbed TLS all versions before 3.0.0, 2.27.0 or 2.16.11 allows attackers with access to precise enough timing and memory access information typically an untrusted operating system attacking ...

PT-2025-48508

An issue was discovered in Mbed TLS before 2.25.0 and before 2.16.9 LTS and before 2.7.18 LTS. The calculations performed by mbedtls mpi exp mod are not limited; thus, supplying overly large parameters could lead to denial of service when generating Diffie-Hellman key pairs...

Mbed TLS mbedtls_mpi_exp_mod Disclosure

The vulnerability of the mbedtlsmpiexpmod function in the Mbed TLS software is related to the use of cryptographic algorithms that contain vulnerabilities. Exploiting this vulnerability could allow an attacker to disclose the protected information...

DEBIAN-CVE-2021-36647

Use of a Broken or Risky Cryptographic Algorithm in the function mbedtlsmpiexpmod in lignum.c in Mbed TLS Mbed TLS all versions before 3.0.0, 2.27.0 or 2.16.11 allows attackers with access to precise enough timing and memory access information typically an untrusted operating system attacking a...

MBed TLS encryption vulnerability

Mbed TLS is an open source, portable, easy to use, readable and flexible SSL library. A security vulnerability exists in Mbed TLS versions prior to 3.0.0, which stems from the use of a dangerous cryptographic algorithm in the mbedtlsmpiexpmod function of lignum.c. The vulnerability is caused by t...

mbedtls_mpi_exp_mod TLS DoS

The vulnerability of the mbedtlsmpiexpmod function in TLS and SSL protocol implementations is related to the lack of data size limitations during calculations. Exploiting this vulnerability allows a remote attacker to cause service failures...

PT-2020-22815

Name of the Vulnerable Software and Affected Versions mbedTLS affected versions not specified Description The issue concerns several security-related problems. One problem is related to the size of calculations performed by mbedtls mpi exp mod, which could lead to a potential denial of service wh...
