Subject: [PATCH] totemsrp: Fix integer overflow in memb_join_sanity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This commit addresses an integer overflow (wraparound) vulnerability
in the check_memb_join_sanity function.
Previously, the 32-bit unsigned network values proc_list_entries and
failed_list_entries were added together before being promoted to
size_t. This allowed the addition to wrap around in 32-bit arithmetic
(e.g., 0x80000000 + 0x80000000 = 0), resulting in a required_len
calculation that was incorrectly small.
The solution is to cast the list entries to size_t and verify that
neither exceeds the maximum allowed value before the addition occurs.
