Subject Name:            Sendmail
Subject Summary:         Mail Transfer Agent
Subject Home:            http://www.sendmail.org/
Subject Versions:        * <= 8.12.8

Vulnerability Id:        CVE-2003-0161
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           remote network
Attack Impact:           privilege escalation

Description:
    Michal Zalewski discovered [1] a confirmed [2] buffer overflow
    vulnerability in all version of the Sendmail [0] MTA earlier than
    8.12.9. The mail address parser performs insufficient bounds checking
    in certain conditions due to a "char" to "int" data type conversion,
    making it possible for an attacker to take control of the application.
    Attackers may remotely exploit this vulnerability to gain "root"
    access of any vulnerable Sendmail server.
