EulerOS Virtualization for ARM 64 3.0.6.0 : libidn2 (EulerOS-SA-2020-1338)

high Nessus Plugin ID 135125

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing a security update.

Description

According to the version of the libidn2 package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerability :

 - GNU libidn2 before 2.2.0 fails to perform the roundtrip checks specified in RFC3490 Section 4.2 when converting A-labels to U-labels. This makes it possible in some circumstances for one domain to impersonate another. By creating a malicious domain that matches a target domain except for the inclusion of certain punycoded Unicode characters (that would be discarded when converted first to a Unicode label and then back to an ASCII label), arbitrary domains can be impersonated.(CVE-2019-12290)

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 libidn2 package.
