Just looked quickly a bit ... I spotted some sprintf() which are unsafe, especially when dealing with DB string or blobs, the target buffer is 255 bytes in size, but I haven't seen any check of input size. This snippet needs some checks as well, for allocated pointer and snprintf: ``` + int username_size=VAL_STR(tval).len+1*sizeof(char); + username = (char*)pkg_malloc(username_size); + snprintf(username,username_size,"%s",VAL_STR(tval).s); ``` `pkg_strdup()` can return NULL, but that is not checked -- although, I didn't looked more to see if it always safe to work further if the return is NULL there. I will ask to see if anyone else can do additional work to review. If not, as I said, I do not have anything against merging it. -- You are receiving this because you are subscribed to this thread.
