Fixed bug 1953 - Crash at memcpy X11_DispatchEvent(_THIS) Function
Nitz
In Function X11_DispatchEvent(_THIS), case SelectionNotify :
static void
X11_DispatchEvent(_THIS)
{
// Some Code
case SelectionNotify: {
//Some Code
SDL_bool expect_lf = SDL_FALSE;
char *start = NULL; // Initialised with NULL
char *scan = (char*)p.data;
char *fn;
char *uri;
int length = 0;
while (p.count--) {
if (!expect_lf) {
if (*scan==0x0D) {
expect_lf = SDL_TRUE;
} else if(start == NULL) {
start = scan;
length = 0;
}
length++;
} else {
if (*scan==0x0A && length>0) {
uri = malloc(length--);
memcpy(uri, start, length); // Problem is Here, start is still NULL if control comes to else statement without initialising the start pointer, which is wrong
uri[length] = 0;
fn = X11_URIToLocal(uri);
if (fn) SDL_SendDropFile(fn);
free(uri);
}
expect_lf = SDL_FALSE;
start = NULL;
}
scan++;
}
}
As shown above how start pointer remains NULL, Patch for this issue would be:
if (*scan==0x0D) {
expect_lf = SDL_TRUE;
}
if(start == NULL) {
start = scan;
length = 0;
}
Just replace else if statement with if.
