  1. Revision: 6480 Description of bug: Some usernames can't login to mangos-realmd, even if they put correct password. Example of such username is "kreved" How to repeat: 1) run mangos-world 2) type "create kreved somepassword somepassword" 3) run mangos-realmd 4) Run client and try to login Other information: This bug activates when sha1(username) ends with 0x00 (For example sha1("KREVED") = 901b43e4f42ce49ba47b112ab70f6f554e9c4400) this 0x00 is lost when "t4.SetBinary(sha.GetDigest(), 20);" Patch: Index: src/realmd/AuthSocket.cpp =================================================================== --- src/realmd/AuthSocket.cpp (revision 6480) +++ src/realmd/AuthSocket.cpp (working copy) @@ -622,11 +622,13 @@ sha.Initialize(); sha.UpdateData(_login); sha.Finalize(); - BigNumber t4; - t4.SetBinary(sha.GetDigest(), 20); + uint8 t4[sHA_DIGEST_LENGTH]; + memcpy(t4, sha.GetDigest(), SHA_DIGEST_LENGTH); sha.Initialize(); - sha.UpdateBigNumbers(&t3, &t4, &s, &A, &B, &K, NULL); + sha.UpdateBigNumbers(&t3, NULL); + sha.UpdateData(t4, SHA_DIGEST_LENGTH); + sha.UpdateBigNumbers(&s, &A, &B, &K, NULL); sha.Finalize(); BigNumber M; M.SetBinary(sha.GetDigest(), 20);
