Does anyone successfuly exploited any format string vulnerability on PA-RISC architecture (on any other archjitecture with aligned memory access)??? I mean: does architecture here prevents from exploiting it? Format string exploitation using %n requires (let's say) 4 unaligned memory writes to overwrite address in memory. If i try to write to unaligned address i'm getting SIGBUS. Does anyone has any ideas? -- Mariusz Wołoszyn Internet Security Specialist, Internet Partners
