Red Hat Security Advisory: Red Hat Advanced Cluster Management for Kubernetes v2.14.3 security update

Important

A flaw was found in Lodash. A prototype pollution vulnerability in the _.unset and _.omit functions allows an attacker able to control property paths to delete methods from global prototypes. By removing essential functionalities, this can result in a denial of service.

CWE-1321 - Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')

A flaw was found in database/sql. Concurrent queries can produce unexpected results when a query is cancelled during a Scan method call on returned Rows, creating a race condition. This vulnerability allows an attacker who can initiate and cancel queries to trigger this condition, possibly leading to inconsistent data being returned to the application.

CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

A flaw was found in Apache Thrift c_glib language bindings. A remote attacker could send specially crafted requests to a c_glib-based Thrift server, leading to a mismatched memory management routines vulnerability. This could cause the server to crash with a "free(): invalid pointer" error, resulting in a Denial of Service (DoS).

CWE-763 - Release of Invalid Pointer or Reference

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 golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the `HostnameError.Error()` function. This flaw, caused by unbounded string concatenation, leads to excessive resource consumption. Successful exploitation can result in a denial of service (DoS) for the affected system.

CWE-1050 - Excessive Platform Resource Consumption within a Loop
