EulerOS 2.0 SP2 : python-crypto (EulerOS-SA-2021-1351)

high Nessus Plugin ID 146674

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the python-crypto package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected python-crypto package.
