Vulnerability Id:        CVE-2004-1011, CVE-2004-1012, CVE-2004-1013,
                         CVE-2004-1015
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           remote network
Attack Impact:           arbitrary code execution

Description:
    According to a security advisory from Stefan Esser [0], several
    vulnerabilities exist in Cyrus imapd. The updated OpenPKG packages fix
    all these problems.
    
    When the option "IMAPMAGICPLUS" is activated on a server, the
    "PROXY" and "LOGIN" commands suffer a standard stack overflow,
    because the username is not checked against a maximum length.
    CVE-2004-1011
    
    Due to a bug within the argument parser of the "PARTIAL" command
    buffer positions outside the allocated memory buffer may be accessed.
    CVE-2004-1012
    
    The argument parser of the "FETCH" command suffers a similar bug.
    CVE-2004-1013
    
    Under memory allocation failure conditions the "cmd_append" handler
    supporting "MULTIAPPENDS" may enter code paths doing post increments
    whose behavior is undefined in ANSI C. The same function also suffers
    from a integer wrap. No CVE id.
    
    Another "IMAPMAGICPLUS" overflow was later discovered by Thomas
    Klaeger in proxyd.c "proxyd_canon_user" function. CVE-2004-1015
    
    Sebastian Krahmer mentioned a missing NUL-termination in global.c and
    provided a patch. No CVE id.
