    Arch Linux Security Advisory ASA-202010-11
    ==========================================
    
    Severity: High
    Date    : 2020-10-20
    CVE-ID  : CVE-2020-15999
    Package : lib32-freetype2
    Type    : arbitrary code execution
    Remote  : Yes
    Link    : https://security.archlinux.org/AVG-1255
    
    Summary
    =======
    
    The package lib32-freetype2 before version 2.10.4-1 is vulnerable to
    arbitrary code execution.
    
    Resolution
    ==========
    
    Upgrade to 2.10.4-1.
    
    # pacman -Syu "lib32-freetype2>=2.10.4-1"
    
    The problem has been fixed upstream in version 2.10.4.
    
    Workaround
    ==========
    
    None.
    
    Description
    ===========
    
    A heap buffer overflow has been found in freetype2 before 2.10.4.
    Malformed TTF files with PNG sbit glyphs can cause a heap buffer
    overflow in Load_SBit_Png as libpng uses the original 32-bit values,
    which are saved in png_struct. If the original width and/or height are
    greater than 65535, the allocated buffer won't be able to fit the
    bitmap.
    
    Impact
    ======
    
    A remote user can serve malformed TTF files that can cause arbitrary
    code execution on the affected host.
