Summary
Red Hat Security Advisory: containernetworking-plugins security and bug fix update
Notes
Topic
An update for containernetworking-plugins is now available for Red Hat Enterprise Linux 9.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The Container Network Interface (CNI) project consists of a specification and libraries for writing plug-ins for configuring network interfaces in Linux containers, along with a number of supported plug-ins. CNI concerns itself only with network connectivity of containers and removing allocated resources when the container is deleted.
Security Fix(es):
* golang: html/template: improper handling of JavaScript whitespace (CVE-2023-24540)
* net/http, golang.org/x/net/http2: avoid quadratic complexity in HPACK decoding (CVE-2022-41723)
* golang: crypto/tls: large handshake records may cause panics (CVE-2022-41724)
* golang: net/http, mime/multipart: denial of service from excessive resource consumption (CVE-2022-41725)
* golang: net/http, net/textproto: denial of service from excessive memory allocation (CVE-2023-24534)
* golang: net/http, net/textproto, mime/multipart: denial of service from excessive resource consumption (CVE-2023-24536)
* golang: html/template: backticks not treated as string delimiters (CVE-2023-24538)
* golang: html/template: improper sanitization of CSS values (CVE-2023-24539)
* golang: html/template: improper handling of empty HTML attributes (CVE-2023-29400)
* golang: net/http: insufficient sanitization of Host header (CVE-2023-29406)

Firstly, the vulnerability requires specific conditions to be met: the presence of Go templates within JavaScript template literals. This limits the scope of affected codebases, reducing the likelihood of exploitation. Additionally, the decision to disallow such interactions in future releases of Go indicates a proactive approach to addressing the issue. Furthermore, the affected packages or components within Red Hat Enterprise Linux, such as Conmon, Grafana, and the RHC package, have been assessed and determined not to be impacted due to their specific usage patterns. So the limited scope of affected systems and the absence of exploitation vectors in specific components within Red Hat Enterprise Linux contribute to categorizing the severity of the issue as moderate.\n\nFor Red Hat Enterprise Linux,\n\n* Conmon uses go in unit testing, but not functionally in the package. Go is used only in test files, hence, not in the actual code, thus, conmon is not affected.\n* The Go templates in Grafana do not contain any javascript.
