EulerOS 2.0 SP8 : nss (EulerOS-SA-2020-2478)

high Nessus Plugin ID 143254

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

- A flaw was found in the way NSS handled CCS (ChangeCipherSpec) messages in TLS 1.3. This flaw allows a remote attacker to send multiple CCS messages, causing a denial of service for servers compiled with the NSS library. The highest threat from this vulnerability is to system availability. This flaw affects NSS versions before 3.58.(CVE-2020-25648)

- In Network Security Services before 3.44, a malformed Netscape Certificate Sequence can cause NSS to crash, resulting in a denial of service.(CVE-2019-17007)

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 packages.
