loadmodule in SunOS 4.1.x, as used by xnews, does not properly sanitize its environment, which allows local users to gain privileges, a different vulnerability than CVE-1999-1584.

SunOS sendmail 5.59 through 5.65 uses popen to process a forwarding host argument, which allows local users to gain root privileges by modifying the IFS (Internal Field Separator) variable and passing crafted values to the -oR option.

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.

/usr/5bin/su in SunOS 4.1.3 and earlier uses a search path that includes the current working directory (.), which allows local users to gain privileges via Trojan horse programs.

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.
