Red Hat Security Advisory: Satellite 6.16.7 Async Update

Important

Scrapy are vulnerable to a denial of service (DoS) attack due to a flaw in its brotli decompression implementation. The protection mechanism against decompression bombs fails to mitigate the brotli variant, allowing remote servers to crash clients with less than 80GB of available memory. This occurs because brotli can achieve extremely high compression ratios for zero-filled data, leading to excessive memory consumption during decompression.

CWE-400 - Uncontrolled Resource Consumption

A flaw was found in Django. A remote attacker can exploit this vulnerability by sending a crafted request containing multiple duplicate headers to the ASGIRequest component. This can lead to a potential Denial of Service (DoS), making the affected system unavailable to legitimate users.

CWE-167 - Improper Handling of Additional Special Element

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security (TLS) session resumption when certificate authority (CA) settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing a client or server to establish a connection that should have been rejected. This could lead to an authentication bypass under specific conditions.

A flaw was found in rubyipmi, a gem used in the Baseboard Management Controller (BMC) component of Red Hat Satellite. An authenticated attacker with host creation or update permissions could exploit this vulnerability by crafting a malicious username for the BMC interface. This could lead to remote code execution (RCE) on the system.

CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
