    Synopsis
    ========
    
    A buffer overflow in FreeType might allow remote attacker(s) to execute
    arbitrary code.
    
    Background
    ==========
    
    FreeType is a high-quality and portable font engine.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  media-libs/freetype        < 2.10.3-r1              >= 2.10.3-r1
    
    Description
    ===========
    
    A flaw in FreeType's handling of embedded PNG bitmaps was discovered
    where the image height and width was not checked to be within bounds.
    
    Impact
    ======
    
    A remote attacker could entice a user to open a specially crafted font
    file using FreeType possibly resulting in the execution of arbitrary
    code with the privileges of the process or a Denial of Service
    condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All FreeType users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-libs/freetype-2.10.3-r1"
