ISS X-Force Database: nfsutils-hostctl-security-bypass(45895): Red Hat nfs-utils host

Red Hat nfs-utils host_ctl security bypass

nfsutils-hostctl-security-bypass (45895)

Medium Risk

Description:

The Red Hat nfs-utils package could allow a remote attacker to bypass security restrictions. The host_ctl function is called using arguments in improper order, which causes TCP Wrappers to fail to honor Netgroups. A remote attacker could exploit this vulnerability to bypass access restrictions and possibly launch further attacks against the system.
