AlmaLinux 9.2 [TuxCare] Security Update: grafana-pcp Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2026:1772040065)

high Nessus Plugin ID 361966

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1772040065 advisory.

 - The net/url package does not set a limit on the number of query parameters in a query. While the maximum size of query parameters in URLs is generally limited by the maximum request header size, the net/http.Request.ParseForm method can parse large URL-encoded forms. Parsing a large form containing many unique query parameters can cause excessive memory consumption. (CVE-2025-61726)

 - Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption. (CVE-2025-61729)

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

Solution

Update the affected grafana-pcp package based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2026:1772040065.
