Out of bounds read (Buffer overrun) #390

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
In items.c, a buffer overrun may occur due to incorrect calculation.

7. cond_between: Checking sid > 200U implies that sid has the value which is 
between 1 and 200 (inclusive) on the false branch.
 926            if (!safe_strtoul(p, &sid) || sid < POWER_SMALLEST

8. overrun-local: Overrunning array tocrawl of 200 bytes at byte offset 200 
using index sid (which evaluates to 200).
 932            tocrawl[sid] = 1;

Thanks,
