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).

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.

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.

The installation of Sun Source (sunsrc) tapes allows local users to gain root privileges via setuid root programs (1) makeinstall or (2) winstall.

Vulnerability in in.telnetd in SunOS 4.1.1 and earlier allows local users to gain root privileges.

Vulnerability in /bin/mail in SunOS 4.1.1 and earlier allows local users to gain root privileges via certain command line arguments.

rpc.pwdauthd in SunOS 4.1.1 and earlier does not properly prevent remote access to the daemon, which allows remote attackers to obtain sensitive system information.

TIOCCONS in SunOS 4.1.1 does not properly check the permissions of a user who tries to redirect console output and input, which could allow a local user to gain privileges.

The SunView (SunTools) selection_svc facility allows remote users to read files.
