Subject Name:            PHP
Subject Summary:         Personal HomePage (PHP)
Subject Home:            http://www.php.net/
Subject Versions:        * <= 4.3.1

Vulnerability Id:        CVE-2002-0985, CVE-2002-0986, CVE-2003-0442
Vulnerability Scope:     global (not OpenPKG specific)

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

Description:
    A security advisory [3] states that in PHP [1] version 4.3.1 (but
    we at OpenPKG believe 4.2.x) and earlier, when transparent session
    ID support is enabled using the "session.use_trans_sid" option,
    the session ID is not escaped before use, which allows remote
    attackers to insert arbitrary script via the PHPSESSID parameter.
    
    Additionally, Wojciech Purczynski some time ago found out [2] that
    it is possible to allow remote attackers to by-pass "safe mode"
    restrictions in PHP [1] 4.x to 4.2.2 and modify command line arguments
    to the MTA (e.g. sendmail) in the 5th argument to mail(), altering MTA
    behavior and possibly executing commands. CVE-2002-0985
    
    Wojciech Purczynski also reported [2] that the mail function in
    PHP [1] 4.x to 4.2.2 does not filter ASCII control characters from
    its arguments, which could allow remote attackers to modify mail
    message content, including mail headers, and possibly use PHP as a
    "spam proxy." CVE-2002-0986
