Subject: [PATCH 1/3] Protect array_list_del_idx against size_t overflow.
|
||||
|
||||
If the assignment of stop overflows due to idx and count being
|
||||
larger than SIZE_T_MAX in sum, out of boundary access could happen.
|
||||
|
||||
It takes invalid usage of this function for this to happen, but
|
||||
I decided to add this check so array_list_del_idx is as safe against
|
||||
bad usage as the other arraylist functions.

Subject: [PATCH 2/3] Prevent division by zero in linkhash.
|
||||
|
||||
If a linkhash with a size of zero is created, then modulo operations
|
||||
are prone to division by zero operations.
|
||||
|
||||
Purely protective measure against bad usage.

Subject: [PATCH 3/3] Fix integer overflows.
|
||||
|
||||
The data structures linkhash and printbuf are limited to 2 GB in size
|
||||
due to a signed integer being used to track their current size.
|
||||
|
||||
If too much data is added, then size variable can overflow, which is
|
||||
an undefined behaviour in C programming language.
|
||||
|
||||
Assuming that a signed int overflow just leads to a negative value,
|
||||
like it happens on many sytems (Linux i686/amd64 with gcc), then
|
||||
printbuf is vulnerable to an out of boundary write on 64 bit systems.
