VAR-202108-1243

Vulnerability from variot - Updated: 2024-08-14 14:11

A memory corruption issue was addressed with improved input validation. This issue is fixed in macOS Big Sur 11.6, watchOS 8, tvOS 15, iOS 14.8 and iPadOS 14.8, iOS 15 and iPadOS 15. Processing a maliciously crafted image may lead to arbitrary code execution. iPadOS , iOS , macOS Multiple Apple products have an out-of-bounds write 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 disclose sensitive information on affected installations of Apple macOS. Interaction with the CoreGraphics library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.The specific flaw exists within the parsing of PDF files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated data structure. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. ** REJECT ** DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: none. Reason: This candidate was withdrawn by the CVE program. Notes: none
