    DATE: Wed, 24 Aug 2005 10:44:26 +0200
    Az Evolution több format string hibát is tartalmaz a vCard valamint az
    LDAP szerverektől vett kontakt adatok megjelenítő kódjában. Ugyancsak
    hiba, hogy a program nem megfelelően kezeli bizonyos naptár bejegyzéseket.
    Gentoo kijött a csomag javításával.

    Synopsis
    ========
    
    Evolution is vulnerable to format string vulnerabilities which may
    result in remote execution of arbitrary code.
    
    Background
    ==========
    
    Evolution is a GNOME groupware application.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package                /  Vulnerable  /                Unaffected
        -------------------------------------------------------------------
      1  mail-client/evolution     < 2.2.3-r3                  >= 2.2.3-r3
    
    Description
    ===========
    
    Ulf Harnhammar discovered that Evolution is vulnerable to format string
    bugs when viewing attached vCards and when displaying contact
    information from remote LDAP servers or task list data from remote
    servers (CAN-2005-2549). He also discovered that Evolution fails to
    handle special calendar entries if the user switches to the Calendars
    tab (CAN-2005-2550).
    
    Impact
    ======
    
    An attacker could attach specially crafted vCards to emails or setup
    malicious LDAP servers or calendar entries which would trigger the
    format string vulnerabilities when viewed or accessed from Evolution.
    This could potentially result in the execution of arbitrary code with
    the rights of the user running Evolution.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All Evolution users should upgrade to the latest version:
    
        # emerge --sync
        # emerge --ask --oneshot --verbose ">=mail-client/evolution-2.2.3-r3"
