EulerOS Virtualization 2.9.0 : krb5 (EulerOS-SA-2021-1641)

high Nessus Plugin ID 147679

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the version of the krb5 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :

 - MIT Kerberos 5 (aka krb5) before 1.17.2 and 1.18.x before 1.18.3 allows unbounded recursion via an ASN.1-encoded Kerberos message because the lib/krb5/asn.1/asn1_encode.c support for BER indefinite lengths lacks a recursion limit.(CVE-2020-28196)

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 krb5 package.
