CWE: CWE-668 \u2014 Exposure of Resource to Wrong Sphere
The product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource.

Code:
int anetUnixServer(char *err, char *path, mode_t perm, int backlog)
{
    int s;
    struct sockaddr_un sa;

    if (strlen(path) > sizeof(sa.sun_path)-1) {
        anetSetError(err,"unix socket path too long (%zu), must be under %zu", strlen(path), sizeof(sa.sun_path));
        return ANET_ERR;
    }
    if ((s = anetCreateSocket(err,AF_LOCAL)) == ANET_ERR)
        return ANET_ERR;

    memset(&sa,0,sizeof(sa));
    sa.sun_family = AF_LOCAL;
    redis_strlcpy(sa.sun_path,path,sizeof(sa.sun_path));
    if (anetListen(err,s,(struct sockaddr*)&sa,sizeof(sa),backlog,perm) == ANET_ERR)
        return ANET_ERR;
    return s;
