TITLE

plural  Apple  Product out-of-bounds read vulnerability

DESCRIPTION

An out-of-bounds read was addressed with improved bounds checking. This issue is fixed in tvOS 14.6, iOS 14.6 and iPadOS 14.6, Security Update 2021-003 Catalina, macOS Big Sur 11.4, watchOS 7.5. Processing a maliciously crafted audio file may disclose restricted memory. plural Apple The product contains an out-of-bounds read vulnerability.Information may be obtained. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Apple macOS. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the USACBitstreamReader function in AudioCodecs. Crafted data in a LOAS file can trigger an overflow of a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. Apple tvOS is a smart TV operating system developed by Apple (Apple). There is a buffer error vulnerability in Apple tvOS, which originates from the boundary conditions of the coreaudio subsystem. A remote attacker could exploit this vulnerability to create a specially crafted audio file, trick the victim into opening it, trigger an out-of-bounds read error , and read the contents of memory on the system. The vulnerability could allow a remote attacker to gain access to potentially sensitive information. Affected products and versions: tvOS: 14.0 18J386, 14.0.1 18J400, 14.0.2 18J411, 14.2 18K57, 14.3 18K561, 14.4 18K802, 14.5 18L204. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2021-05-25-1 iOS 14.6 and iPadOS 14.6 iOS 14.6 and iPadOS 14.6 addresses the following issues.
