CVE-2020-9793

Remote code execution via improper input validation

Published Jun 9, 2020 · Updated Aug 4, 2024

Memory corruption in Apple iOS, macOS, tvOS, and watchOS allows remote attackers to execute arbitrary code via crafted input. On macOS, Apple locates the flaw in the bundled Python component, which inadequately validates untrusted input before memory handling; no affected function or input format is public. Affected releases precede iOS and iPadOS 13.5, Catalina 10.15.5, tvOS 13.4.5, and watchOS 6.2.5, and exploitation requires user interaction.
