glibc: denial of service

clntudpcall allocates a buffer, using alloca, to store the payload of an incoming socket error. If a malicious server floods the client with crafted ICMP and UDP packets, this can cause the client to allocate sufficiently many such temporary buffers to cause a stack frame overflow denial of...
