NewStart CGSL MAIN 6.02 : krb5 Vulnerability (NS-SA-2022-0057)

high Nessus Plugin ID 160870

Synopsis

The remote NewStart CGSL host is affected by a vulnerability.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has krb5 packages installed that are affected by a 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 Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL krb5 packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
