Previously IP resolution + could fail if HTTP headers were transferred separately from the data + (for whatever reason). Jonathan Schulz submitted a patch for this. + - [server] Replay attack bug fix to ensure that an attacker cannot force a + replay attack by intercepting an SPA packet and the replaying it with the + base64 version of "Salted__" (for Rindael) or the "hQ" prefix (for + GnuPG). This is an important fix. The following comment was added into + the fwknopd code: + + /* Ignore any SPA packets that contain the Rijndael or GnuPG prefixes + * since an attacker might have tacked them on to a previously seen + * SPA packet in an attempt to get past the replay check. And, we're + * no worse off since a legitimate SPA packet that happens to include + * a prefix after the outer one is stripped off won't decrypt properly + * anyway because libfko would not add a new one. + */ + + - [server] Fixed a memory leak bug in the replay attack detection code. + The leak was found with the test suite in --enable-valgrind mode, and + here is the valgrind trace that exposed it: + + 44 bytes in 1 blocks are definitely lost in loss record 2 of 2 + at 0x482BE68: malloc (in + /usr/lib/valgrind/vgpreload_memcheck-x86-linux.so) + by 0x490EA50: strdup (strdup.c:43) + by 0x10CD69: incoming_spa (incoming_spa.c:162) + by 0x10E000: process_packet (process_packet.c:200) + by 0x4862E63: ???
