EulerOS 2.0 SP9 : libgcrypt (EulerOS-SA-2021-2922)

medium Nessus Plugin ID 156416

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the libgcrypt package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- The ElGamal implementation in Libgcrypt before 1.9.4 allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous combination of the prime defined by the receiver's public key, the generator defined by the receiver's public key, and the sender's ephemeral exponents can lead to a cross-configuration attack against OpenPGP. (CVE-2021-40528)

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 libgcrypt packages.
