Trust: 0.8

sources: JVNDB: JVNDB-2020-009937

DESCRIPTION

An out-of-bounds write issue was addressed with improved bounds checking. 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. Processing a maliciously crafted audio file may lead to arbitrary code execution. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Apple macOS. Interaction with the AudioToolbox library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.The specific flaw exists within the AudioToolbox framework. Crafted data in a CAF file can trigger a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. A security vulnerability exists in the Clang component of Apple macOS Catalina versions prior to 10.15.6. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2020-07-15-2 macOS Catalina 10.15.6, Security Update 2020-004 Mojave, Security Update 2020-004 High Sierra macOS Catalina 10.15.6, Security Update 2020-004 Mojave, Security Update 2020-004 High Sierra are now available and address the following: Audio Available for: macOS Catalina 10.15.5 Impact: Processing a maliciously crafted audio file may lead to arbitrary code execution Description: An out-of-bounds write issue was addressed with improved bounds checking.
