Vulnerability from variot

A stack overflow was addressed with improved input validation. This issue is fixed in iOS 14.7, macOS Big Sur 11.5, watchOS 7.6, tvOS 14.7, Security Update 2021-005 Mojave, Security Update 2021-004 Catalina. Processing a maliciously crafted font 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 libType1Scaler library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.The specific flaw exists within the parsing of PFB fonts. A crafted PFB font can trigger an overflow of a fixed-length 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 macOS is a set of dedicated operating systems developed by Apple Corporation for Mac computers.

    "data": "A stack overflow was addressed with improved input validation. This issue is fixed in iOS 14.7, macOS Big Sur 11.5, watchOS 7.6, tvOS 14.7, Security Update 2021-005 Mojave, Security Update 2021-004 Catalina. Processing a maliciously crafted font 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 libType1Scaler library is required to exploit this vulnerability but attack vectors may vary depending on the implementation.The specific flaw exists within the parsing of PFB fonts. A crafted PFB font can trigger an overflow of a fixed-length 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. \nThere is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. Apple macOS is a set of dedicated operating systems developed by Apple Corporation for Mac computers.
