CVE-2018-1084 corosync: Integer overflow in exec/totemcrypto.c:authenticate_nss_2_3() function
Potential pre-authentication buffer overflow due to integer overflow in
exec/totemcrypto.c:authenticate_nss_2_3() function can lead to denial of
service or potentially to remote code execution.
Vulnerable code:
static int authenticate_nss_2_3 (
struct crypto_instance *instance,
unsigned char *buf,
int *buf_len)
{
if (hash_to_nss[instance->crypto_hash_type]) {
unsigned char tmp_hash[hash_len[instance->crypto_hash_type]];
int datalen = *buf_len - hash_len[instance->crypto_hash_type];
if (calculate_nss_hash(instance, buf, datalen, tmp_hash) < 0) {
return -1;
}
