HP ypbind allows attackers with root privileges to modify NIS data.

NFS on SunOS 4.1 through 4.1.2 ignores the high order 16 bits in a 32 bit UID, which allows a local user to gain root access if the lower 16 bits are set to 0, as fixed by the NFS jumbo patch upgrade.

Cisco IOS 9.1 and earlier does not properly handle extended IP access lists when the IP route cache is enabled and the "established" keyword is set, which could allow attackers to bypass filters.

Vulnerability in Cisco routers versions 8.2 through 9.1 allows remote attackers to bypass access control lists when extended IP access lists are used on certain interfaces, the IP route cache is enabled, and the access list uses the "established" keyword.

Vulnerability in Monitor utility (SYS$SHARE:SPISHR.EXE) in VMS 5.0 through 5.4-2 allows local users to gain privileges.

Denial of service by sending forged ICMP unreachable packets.

Vulnerability in integer multiplication emulation code on SPARC architectures for SunOS 4.1 through 4.1.2 allows local users to gain root access or cause a denial of service (crash).

The portmapper may act as a proxy and redirect service requests from an attacker, making the request appear to come from the local host, possibly bypassing authentication that would otherwise have taken place. For example, NFS file systems could be mounted through the portmapper despite export restrictions.

SunOS 4.1.2 and earlier allows local users to gain privileges via "LD_*" environmental variables to certain dynamically linked setuid or setgid programs such as (1) login, (2) su, or (3) sendmail, that change the real and effective user ids to the same user.

FTP installation script anon.ftp in AIX insecurely configures anonymous FTP, which allows remote attackers to execute arbitrary commands.

AIX passwd allows local users to gain root access.

The default configuration for UUCP in AIX before 3.2 allows local users to gain root privileges.

The rexd service is running, which uses weak authentication that can allow an attacker to execute commands.

Vulnerability in rexec daemon (rexecd) in AT&T TCP/IP 4.0 for various SVR4 systems allows remote attackers to execute arbitrary commands.

Vulnerability in LAT/Telnet Gateway (lattelnet) on Ultrix 4.1 and 4.2 allows attackers to gain root privileges.

Vulnerability in crp in Hewlett Packard Apollo Domain OS SR10 through SR10.3 allows remote attackers to gain root privileges via insecure system calls, (1) pad_$dm_cmd and (2) pad_$def_pfk().

In SunOS, NFS file handles could be guessed, giving unauthorized access to the exported file system.

rdist in various UNIX systems uses popen to execute sendmail, which allows local users to gain root privileges by modifying the IFS (Internal Field Separator) variable.

TFTP is not running in a restricted directory, allowing a remote attacker to access sensitive information such as password files.

The default configuration of NCSA Telnet package for Macintosh and PC enables FTP, even though it does not include an "ftp=yes" line, which allows remote attackers to read and modify arbitrary files.
