Sun SunOS 4.1 through 4.1.3 allows local attackers to gain root access via insecure permissions on files and directories such as crash.
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.
Vulnerability in /bin/mail in SunOS 4.1.1 and earlier allows local users to gain root privileges via certain command line arguments.
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).
passwd in SunOS 4.1.x allows local users to overwrite arbitrary files via a symlink attack and the -F command line argument.
cmdtool in OpenWindows 3.0 and XView 3.0 in SunOS 4.1.4 and earlier allows attackers with physical access to the system to display unechoed characters (such as those from password prompts) via the L2/AGAIN key.
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.
The permissions for the /dev/audio device on Solaris 2.2 and earlier, and SunOS 4.1.x, allow any local user to read from the device, which could be used by an attacker to monitor conversations happening near a machine that has a microphone.
The installation of Sun Source (sunsrc) tapes allows local users to gain root privileges via setuid root programs (1) makeinstall or (2) winstall.
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.
Malicious option settings in UDP packets could force a reboot in SunOS 4.1.3 systems.
Denial of service by sending forged ICMP unreachable packets.
The SunView (SunTools) selectionsvc facility allows remote users to read files.
NFS cache poisoning.
Sun/Solaris utmp file allows local users to gain root access if it is writable by users other than root.
pcnfsd (aka rpc.pcnfsd) allows local users to change file permissions, or execute arbitrary commands through arguments in the RPC call.
