Category:Huawei EulerOS Local Security Checks
Title:Huawei EulerOS: Security Advisory for python-crypto (EulerOS-SA-2021-2118)
Summary:The remote host is missing an update for the Huawei EulerOS 'python-crypto' package(s) announced via the EulerOS-SA-2021-2118 advisory.
Description:Summary:
The remote host is missing an update for the Huawei EulerOS 'python-crypto' package(s) announced via the EulerOS-SA-2021-2118 advisory.

Vulnerability Insight:
lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for PyCrypto's ElGamal implementation.(CVE-2018-6594)

Affected Software/OS:
'python-crypto' package(s) on Huawei EulerOS Virtualization for ARM 64 3.0.2.0.

Solution:
Please install the updated package(s).

CVSS Score:
5.0

CVSS Vector:
