Buffer overflow in BSD-based telnetd telnet daemon on various operating systems allows remote attackers to execute arbitrary commands via a set of options including AYT (Are You There), which is not properly handled by the telrcv function.
Buffer overflow in whodo in Solaris SunOS 5.5.1 through 5.8 allows local users to execute arbitrary code via a long (1) SOR or (2) CFIME environment variable.
FTP server in Solaris 8 and earlier allows local and remote attackers to cause a core dump in the root directory, possibly with world-readable permissions, by providing a valid username with an invalid password followed by a CWD ~ command, which could release sensitive information such as shadowed passwords, or fill the disk partition.
Buffer overflow in /usr/bin/cu in Solaris 2.8 and earlier, and possibly other operating systems, allows local users to gain privileges by executing cu with a long program name (arg0).
