Red Hat Security Advisory: OpenShift Container Platform 4.13.67 bug fix and security update

Important

A flaw was found in the net/url package in the Go standard library. The package does not enforce a limit on the number of unique query parameters it parses. A Go application using the net/http.Request.ParseForm method will try to process all parameters provided in the request. A specially crafted HTTP request containing a massive number of query parameters will cause the application to consume an excessive amount of memory, eventually causing the application to crash or become unresponsive, resulting in a denial of service.

CWE-770 - Allocation of Resources Without Limits or Throttling

A flaw was found in the archive/zip package in the Go standard library. A super-linear file name indexing algorithm is used in the first time a file in an archive is opened. A crafted zip archive containing a specific arrangement of file names can cause an excessive CPU and memory consumption. A Go application processing a malicious archive can become unresponsive or crash, resulting in a denial of service.

CWE-770 - Allocation of Resources Without Limits or Throttling

A flaw was found in cmd/go. An attacker can exploit this by building a malicious Go source file that uses the '#cgo pkg-config:' directive. This allows the attacker to write to an arbitrary file with partial control over its content, by providing a '--log-file' argument to the pkg-config command. This vulnerability can lead to arbitrary file write.

CWE-88 - Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')

A flaw was found in Go's 'cgo tool'. This vulnerability arises from a discrepancy in how Go and C/C++ comments are parsed, which allows for malicious code to be hidden within comments and then "smuggled" into the compiled `cgo` binary. An attacker could exploit this to embed and execute arbitrary code, potentially leading to significant system compromise.
