Title

Уязвимость операционной системы Linux, позволяющая нарушителю вызвать отказ в обслуживании

Description

Уязвимость NFSv2/NFSv3 сервера nfsd подсистемы ядра операционной системы Linux существует из-за недостаточной проверки входных данных. Эксплуатация уязвимости может позволить нарушителю, действующему удалённо, вызвать отказ в обслуживании (системный сбой) с помощью длинного RPC-ответа, связанного с net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c и fs/nfsd/nfsxdr.c.
