Name of the Vulnerable Software and Affected Versions: Windows Graphics Component (affected versions not specified) Description: The issue is related to errors in processing objects in memory within the Windows Graphics Component. It may allow an attacker to disclose protected information. The vulnerability can be exploited to obtain sensitive information and affect the system. Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.

The issue is related to incorrect handling of objects in memory, which can be exploited by running a specially crafted application, allowing an attacker to elevate their privileges. This can affect the system.

The issue is related to memory corruption and buffer overflow, which may lead to arbitrary code execution when processing maliciously crafted web content. This can allow a remote attacker to execute arbitrary code.

The issue is related to errors in handling objects in memory by the ChakraCore JavaScript engine. This could allow a remote attacker to execute arbitrary code, potentially gaining the same user rights as the current user. If the current user has administrative rights, the attacker could take control of the affected system, enabling them to install programs, view, change, or delete data, or create new accounts with full user rights.

Name of the Vulnerable Software and Affected Versions: iOS versions prior to 12.1 tvOS versions prior to 12.1 watchOS versions prior to 5.1 Safari versions prior to 12.0.1 iTunes versions prior to 12.9.1 iCloud for Windows versions prior to 7.8 Description: A memory corruption issue was addressed with improved validation. Recommendations: For iOS versions prior to 12.1, update to version 12.1 or later. For tvOS versions prior to 12.1, update to version 12.1 or later. For watchOS versions prior to 5.1, update to version 5.1 or later. For Safari versions prior to 12.0.1, update to version 12.0.1 or later. For iTunes versions prior to 12.9.1, update to version 12.9.1 or later. For iCloud for Windows versions prior to 7.8, update to version 7.8 or later.

Multiple memory corruption issues were addressed with improved memory handling.

Multiple memory corruption issues were addressed with improved memory handling.

The issue is related to multiple integer overflows in the ` objalloc alloc` function and `objalloc alloc` macro, which can be exploited by remote attackers to cause a denial of service (crash) through vectors related to the addition of `CHUNK HEADER SIZE` to the length. This triggers a heap-based buffer overflow.
