EulerOS 2.0 SP5 : nss-softokn (EulerOS-SA-2019-2175)

medium Nessus Plugin ID 130637

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the nss-softokn packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

 - Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. To discover an ECDSA key, the attacker needs access to either the local machine or a different virtual machine on the same physical host.(CVE-2018-0495)

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 nss-softokn package.
