Red Hat Security Advisory: Release of OpenShift Serverless 1.33.0 security update & enhancements

Moderate

A flaw was found in Go's net/http/cookiejar standard library package. When following an HTTP redirect to a domain that is not a subdomain match or an exact match of the initial domain, an http.Client does not forward sensitive headers such as "Authorization" or "Cookie". For example, a redirect from foo.com to www.foo.com will forward the Authorization header, but a redirect to bar.com will not. A maliciously crafted HTTP redirect could cause sensitive headers to be unexpectedly forwarded.

CWE-200 - Exposure of Sensitive Information to an Unauthorized Actor

A vulnerability was found in the quarkus-core component. Quarkus captures local environment variables from the Quarkus namespace during the application's build, therefore, running the resulting application inherits the values captured at build time. Some local environment variables may have been set by the developer or CI environment for testing purposes, such as dropping the database during application startup or trusting all TLS certificates to accept self-signed certificates. If these properties are configured using environment variables or the .env facility, they are captured into the built application, which can lead to dangerous behavior if the application does not override these values. This behavior only happens for configuration properties from the `quarkus.*` namespace. Application-specific properties are not captured.

CWE-526 - Cleartext Storage of Sensitive Information in an Environment Variable

A flaw was found in Go's crypto/x509 standard library package. Verifying a certificate chain that contains a certificate with an unknown public key algorithm will cause a Certificate.Verify to panic. This issue affects all crypto/tls clients and servers that set Config.ClientAuth to VerifyClientCertIfGiven or RequireAndVerifyClientCert.

CWE-400 - Uncontrolled Resource Consumption

A flaw was found in Go's net/mail standard library package. The ParseAddressList function incorrectly handles comments (text within parentheses) within display names. Since this is a misalignment with conforming address parsers, it can result in different trust decisions made by programs using different parsers.

CWE-115 - Misinterpretation of Input

A flaw was found in Go's html/template standard library package. If errors returned from MarshalJSON methods contain user-controlled data, they may be used to break the contextual auto-escaping behavior of the html/template package, allowing subsequent actions to inject unexpected content into templates.

CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
