VAR-202202-1712
Vulnerability from variot - Updated: 2023-12-18 12:15An out-of-bounds write was addressed with improved input validation. This issue is fixed in macOS Big Sur 11.4, iOS 14.6 and iPadOS 14.6, watchOS 7.5, tvOS 14.6. Processing a maliciously crafted font file may lead to arbitrary code execution. plural Apple The product contains a vulnerability related to out-of-bounds writes.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 execute arbitrary code on affected installations of Apple macOS. Interaction with the libFontParser library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.The specific flaw exists within the parsing of TTF fonts. Crafted data in a TTF font 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. Apple macOS is a set of dedicated operating systems developed by Apple Corporation for Mac computers
