This issue was addressed with improved checks. This issue is fixed in macOS Big Sur 11.2, Security Update 2021-001 Catalina, Security Update 2021-001 Mojave, watchOS 7.3, tvOS 14.4, iOS 14.4 and iPadOS 14.4. Processing a maliciously crafted image may lead to a denial of service. There is a security vulnerability in Apple macOS. The vulnerability stems from insufficient validation of user-supplied input when image files are processed in the ImageIO component in macOS, so this vulnerability exists. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack. Vulnerabilities exist in the following products or versions: macOS 10.3, macOS 10.12.4, macOS 10.12.5, macOS 10.12.6, macOS 10.12.6.2, macOS 10.13, macOS 10.13.1, macOS 10.13.2, macOS 10.13.3, macOS 10.13 .4, macOS 10.13.5, macOS 10.13.6, macOS 10.14, macOS 10.14.1, macOS 10.14.2, macOS 10.14.3, macOS 10.14.4, macOS 10.14.5, macOS 10.14.6, macOS 10.15, macOS 10.15 SU1, macOS 10.15.1, macOS 10.15.2, macOS 10.15.3, macOS 10.15.4, macOS 10.15.4 SU1, macOS 10.15.5, macOS 10.15.5 SU1, macOS 10.15.6, macOS 10.15.6 SU1 , macOS 10.15.7, macOS 10.15.7 SU1, macOS 11.0, macOS 11.0.1, macOS 11.1. Apple macOS is vulnerable to a denial of service, caused by an error in the ImageIO component. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2021-02-01-2 Additional information for APPLE-SA-2021-01-26-1 iOS 14.4 and iPadOS 14.4 iOS 14.4 and iPadOS 14.4 addresses the following issues.

An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in macOS Big Sur 11.2, Security Update 2021-001 Catalina, Security Update 2021-001 Mojave, watchOS 7.3, tvOS 14.4, iOS 14.4 and iPadOS 14.4. Processing a maliciously crafted image may lead to arbitrary code execution. plural Apple The product contains an out-of-bounds read vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Apple macOS. Interaction with the ImageIO library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.The specific flaw exists within the ImageIO framework. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before reading memory. An attacker can leverage this vulnerability to execute code in the context of the current process. A security vulnerability exists in Apple ImageIO due to a boundary error in the handling of image files within the ImageIO component in macOS. A remote attacker could create a specially crafted file that tricks a victim into opening the file with affected software, triggering an out-of-bounds write and executing arbitrary code on the targeted system. Vulnerabilities exist in the following products or versions: macOS 11.0, macOS 11.0.1, macOS 11.1. Information about the security content is also available at https://support.apple.com/HT212147.

MinIO is a High Performance Object Storage released under Apache License v2.0. In MinIO before version RELEASE.2021-01-30T00-20-58Z there is a server-side request forgery vulnerability. The target application may have functionality for importing data from a URL, publishing data to a URL, or otherwise reading data from a URL that can be tampered with. The attacker modifies the calls to this functionality by supplying a completely different URL or by manipulating how URLs are built (path traversal etc.). In a Server-Side Request Forgery (SSRF) attack, the attacker can abuse functionality on the server to read or update internal resources. The attacker can supply or modify a URL which the code running on the server will read or submit data, and by carefully selecting the URLs, the attacker may be able to read server configuration such as AWS metadata, connect to internal services like HTTP enabled databases, or perform post requests towards internal services which are not intended to be exposed. This is fixed in version RELEASE.2021-01-30T00-20-58Z, all users are advised to upgrade. As a workaround you can disable the browser front-end with "MINIO_BROWSER=off" environment variable. Minio is an open source object storage server from MinIO, USA. The product supports the construction of infrastructure for machine learning, analysis, and application data workloads
