The qmailadmin utility, developed by Inter7, is vulnerable to a buffer overflow condition. It is meant to run as a CGI program and is typically installed setuid (owned by root on some systems, regular users on others). qmailadmin fails to implement adequate bounds checking when processing an environment variable, resulting in a buffer overrun condition.
|
|
|
|
It is likely that this can be exploited by malicious local users to elevate privileges.
