NVD Description

Note: Versions mentioned in the description apply only to the upstream libtirpc package and not the libtirpc package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Stack-based buffer overflow in the clntudp_call function in sunrpc/clnt_udp.c in the GNU C Library (aka glibc or libc6) allows remote servers to cause a denial of service (crash) or possibly unspecified other impact via a flood of crafted ICMP and UDP packets.
