A vulnerability in nfs-utils could permit an attacker to execute arbitrary code on the system or cause a denial of service.
The NFS protocol provides remote access to shared files accross networks. The nfs-utils package provides an NFS client and server for Linux systems. Nfs-utils on 64-bit architecture machines contains a stack-based buffer overflow vulnerability. The function "getquotainfo()" in "rquota_server.c" assumes certain values to be 32-bit in size during a call to memcpy(). On a 64-bit machine, this can cause a buffer overflow.
A remote attacker could execute arbitrary code or create a denial-of-service condition on a vulnerable server running nfs-utils.
