| 34 | <PRE>It was 10:25 2003/02/01 +0900 when Andrew Church came up with: | |
| 35 | ><i> I don't see how this could be "exploited" in the | |
| 36 | </I>><i> ordinary sense of the | |
| 37 | </I>><i>word, but it can lead to desynchs. Thanks for pointing the | |
| 38 | </I>><i>problem out. | |

| 40 | That depends on how paranoic you have | |
| 41 | been in your coding... if you forgot to check | |
| 42 | for the validity of an arguments processed | |
| 43 | by the various functions in messages.c, | |
| 44 | maybe among those who are not supposed to | |
| 45 | be ever NULL (the parameter for +k for example, | |
| 46 | the ircd will never propagate a +k without | |
| 47 | a valid key) then it can be exploited to | |
| 48 | crash services via normal commands. | |
