Bug in icecast 2.3.2 (not in stable release but a little later and in trunk) : Null pointer in auth_remove_listener
...affects the last
version in the trunk.
We studied a core dump generated by icecast.
We found that the crash occurred in the following icecast code:
static void auth_remove_listener (auth_t *auth, auth_client *auth_user)
{
client_t *client = auth_user->client;
if (client->auth->release_listener)
client->auth->release_listener (auth_user);
auth_release (client->auth);
client->auth = NULL;
/* client is going, so auth is not an issue at this point */
client->authenticated = 0;
}
Because client->auth was NULL and so it tried to dereference a NULL...
