Azure Linux 3.0 Security Update: application-gateway-kubernetes-ingress / azcopy / cert-manager / coredns / kubernetes (CVE-2025-30204)

high Nessus Plugin ID 233725

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of application-gateway-kubernetes-ingress / azcopy / cert-manager / coredns / kubernetes installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-30204 advisory.

 - golang-jwt is a Go implementation of JSON Web Tokens. Prior to 5.2.2 and 4.5.2, the function parse.ParseUnverified splits (via a call to strings.Split) its argument (which is untrusted data) on periods. As a result, in the face of a malicious request whose Authorization header consists of Bearer followed by many period characters, a call to that function incurs allocations to the tune of O(n) bytes (where n stands for the length of the function's argument), with a constant factor of about 16. This issue is fixed in 5.2.2 and 4.5.2. (CVE-2025-30204)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
