Title: AIX ftp tftp and utftp Core Dump Vulnerability
Severity: HIGH
Description:
Some versions of ftpd, tftpd, and utftpd under AIX use the gets() system call to gather information from standard input (STDIN). The gets() system call has no means to denote size of the string it is handling and allows for an infinite amount of data to be passed into it. The problem lies in that the code in ftpd tftpd and utftpd which takes data from the gets() call places it in a fixed buffer. This buffer can be overflown resulting in the applications dumping core. Because these programs are run as root, the core images may contain critical root owned pieces of memory, such as user names and passwords.
