Astra Linux – Vulnerability in Capstone

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and earlier, the length of Skipdata was not checked for bounds. As a result, a user-provided Skipdata callback could cause the csdisasm/csdisasmiter memcpy function to write more than 24 bytes into csinsn.bytes, leading to a heap buffe...
