Although the first vulnerability is a memory corruption problem where the program calls recv() using a heap buffer and a huge amount of data to copy (like 0x7fffffe8, decided by the attacker) in my tests it didn't result exploitable. ####################################################################### =========== 3) The Code =========== http://aluigi.org/poc/unirpcd_1.zip https://gitlab.com/exploit-database/exploitdb-bin-sploits/-/raw/main/bin-sploits/15260.zip (unirpcd_1.zip) ####################################################################### ====== 4) Fix ====== No fix. ####################################################################### |
