- Fixed the RADIUS PEAP client to use the standard TLS versioning.
- Implementation of a function to fix the MAC address of L3 VPN protocol by entering e.g. "MAC: 112233445566" in the "Notes" field of the user information.
- Implementation of a function to fix the virtual MAC address to be assigned to the L3 VPN client as a string attribute from RADIUS server when authentication.
- Hash() has been removed because it was ambiguous, Md5() and Sha0() are proper replacements.
- HMacMd5() and HMacSha1() now share a common implementation handled by the new Internal_HMac() function.
- NewMd() and MdProcess() now support plain hashing (without the key).
- NewMd(), SetMdKey() and MdProcess() now check the OpenSSL functions' return value and in case of failure a debug message is printed along with the error string, if available.
- SetMdKey()'s return value has been changed from void to bool, so that it's possible to know whether the function succeeded or not.
- MdProcess()' return value has been changed from void to UINT (unsigned int) and the function now returns the number of bytes written by HMAC_Final() or EVP_DigestFinal_ex().
coverity thinks there might be null pointer dereference, make it
happier by removing check (there's a check against NULL in function itself).
condition "a.DataSize <= 1500" is always true
Buffer overread in ParseL2TPPacket()
Memory corruption in IcmpParseResult
Missing bounds check in ParseUDP() can lead to invalid memory access
Out-of-bounds read in IPsec_PPP.c (unterminated string buffer)
Overlapping parameters to memcpy() via StrToIp6()
PACK ReadValue() crash vulnerability
Potential use of uninitialized memory via IPToInAddr6()
4 memory leaks. While the amount of leakage is very small per time, these bugs can finally cause process crash by out of memory. So these bugs must be fixed.
Memory leak in NnReadDnsRecord
Memory leak in RadiusLogin()
Memory leak via ParsePacketIPv4WithDummyMacHeader
Remote memory leak in OpenVPN server code
1 coding improvement. This is not a bug, however, I fixed the code to avoid furture misunderstanding.
RecvAll can return success on failure (leading to use of uninitialized memory)
