    The updated packages fix security vulnerabilities:
    
    There is a floating point exception in the kodak_radc_load_raw function
    in dcraw_common.cpp in LibRaw 0.18.2. It will lead to a remote denial
    of service attack. (CVE-2017-13735)
    
    In LibRaw through 0.18.4, an out of bounds read flaw related to
    kodak_65000_load_raw has been reported in dcraw/dcraw.c and internal/
    dcraw_common.cpp. An attacker could possibly exploit this flaw to
    disclose potentially sensitive memory or cause an application crash.
    (CVE-2017-14608)
    
    A stack-based buffer overflow in the find_green() function of dcraw
    through 9.28, as used in ufraw-batch and many other products, may allow
    a remote attacker to cause a control-flow hijack, denial-of-service, or
    unspecified other impact via a maliciously crafted raw photo file.
    (CVE-2018-19655)
