CVE-2024-37298

A flaw was found in the gorilla/schema package. Running schema.Decoder.Decode() on a struct that has a field of type []struct{...} opens it up to malicious attacks regarding memory allocations, taking advantage of the sparse slice functionality. Any use of schema.Decoder.Decode() on a struct with arrays of other structs could trigger memory exhaustion and lead to a denial of service.

This vulnerability in the gorilla/schema package is a high-severity issue due to its potential to cause a Denial of Service (DoS) attack through memory exhaustion. The schema.Decoder.Decode() function, when processing a struct with fields of type []struct{...}, is susceptible to malicious input that exploits sparse slice functionality. This can result in excessive memory allocations, overwhelming the system's resources and rendering the application unresponsive.

The majority of RHEL utilities are not long-running applications; instead, they are command-line tools. These tools utilize Golang package as build-time dependency, which is why they are classified as having a "Moderate" level of impact.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
