"This update for libraw fixes the following issues :

The following security vulnerabilities were addressed :

  - CVE-2018-5813: Fixed an error within the
    'parse_minolta()' function (dcraw/dcraw.c) that could be
    exploited to trigger an infinite loop via a specially
    crafted file. This could be exploited to cause a
    DoS.(boo#1103200).

  - CVE-2018-5815: Fixed an integer overflow in the
    internal/dcraw_common.cpp:parse_qt() function, that
    could be exploited to cause an infinite loop via a
    specially crafted Apple QuickTime file. (boo#1103206)

  - CVE-2018-5810: Fixed an error within the
    rollei_load_raw() function (internal/dcraw_common.cpp)
    that could be exploited to cause a heap-based buffer
    overflow and subsequently cause a crash. (boo#1103353)

  - CVE-2018-5811: Fixed an error within the
    nikon_coolscan_load_raw() function
    (internal/dcraw_common.cpp) that could be exploited to
    cause an out-of-bounds read memory access and
    subsequently cause a crash. (boo#1103359)

  - CVE-2018-5812: Fixed another error within the
    nikon_coolscan_load_raw() function
    (internal/dcraw_common.cpp) that could be exploited to
    trigger a NULL pointer dereference. (boo#1103360)

  - CVE-2018-5807: Fixed an error within the
    samsung_load_raw() function (internal/dcraw_common.cpp)
    that could be exploited to cause an out-of-bounds read
    memory access and subsequently cause a crash.
