Примеры ассемблерного кода для ZX Spectrum
Я не буду делать длинное вступление. Один знакомый хакер однажды сказал, что 10 строк кода могут быть понятнее и интереснее, чем 1000 слов объяснений. Все эти примеры написаны на ассемблере для архитектуры Z80 и запускаются на ретро-компьютере ZX Spectrum 48k.
Что внутри?Stack-based buffer overflow vulnerability in UDP packet handling in Toxcore (CVE-2021-44847)
A stack-based buffer overflow vulnerability was discovered in Toxcore’s networking code that allows a remote attacker to crash the Toxcore process or potentially execute arbitrary code by sending a specially crafted packet. The vulnerability was assigned CVE-2021-44847 identifier.
All users of Toxcore that don’t have UDP disabled are affected. An attacker, knowing the target’s DHT public key, IP and port, can easily craft a packet exploiting the vulnerability. DHT public key, IP and port are all public information, publicly available on the DHT, so an attacker can target any and all Toxcore users by scraping this information from the DHT. This...
