VAR-202010-1285
Vulnerability from variot - Updated: 2023-12-18 11:50A buffer overflow issue was addressed with improved memory handling. This issue is fixed in iOS 13.6 and iPadOS 13.6, macOS Catalina 10.15.6, tvOS 13.4.8, watchOS 6.2.8, iTunes 12.10.8 for Windows, iCloud for Windows 11.3, iCloud for Windows 7.20. Processing a maliciously crafted image may lead to arbitrary code execution. plural Apple The product is vulnerable to a buffer overflow due to improper memory processing.Arbitrary code can be executed by processing maliciously created images. This vulnerability allows remote attackers to execute arbitrary code 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 JBIG2Bitmap::expand method. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Apple iOS, etc. are all products of Apple (Apple). Apple iOS is an operating system developed for mobile devices. Apple tvOS is a smart TV operating system. Apple iPadOS is an operating system for iPad tablets

"data": "A buffer overflow issue was addressed with improved memory handling. This issue is fixed in iOS 13.6 and iPadOS 13.6, macOS Catalina 10.15.6, tvOS 13.4.8, watchOS 6.2.8, iTunes 12.10.8 for Windows, iCloud for Windows 11.3, iCloud for Windows 7.20. Processing a maliciously crafted image may lead to arbitrary code execution. plural Apple The product is vulnerable to a buffer overflow due to improper memory processing.Arbitrary code can be executed by processing maliciously created images. This vulnerability allows remote attackers to execute arbitrary code 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 JBIG2Bitmap::expand method. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Apple iOS, etc. are all products of Apple (Apple). Apple iOS is an operating system developed for mobile devices. Apple tvOS is a smart TV operating system. Apple iPadOS is an operating system for iPad tablets",
