"The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by
multiple vulnerabilities as referenced in the SUSE-SU-2022:1749-1 advisory.

  - 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 buffer over-read in crop_masked_pixels in dcraw through 9.28 could be used by attackers able to supply
    malicious files to crash an application that bundles the dcraw code or leak private information.
    (CVE-2018-19565)

  - A heap buffer over-read in parse_tiff_ifd in dcraw through 9.28 could be used by attackers able to supply
    malicious files to crash an application that bundles the dcraw code or leak private information.
    (CVE-2018-19566)

  - A floating point exception in parse_tiff_ifd in dcraw through 9.28 could be used by attackers able to
    supply malicious files to crash an application that bundles the dcraw code. (CVE-2018-19567)

  - A floating point exception in kodak_radc_load_raw in dcraw through 9.28 could be used by attackers able to
    supply malicious files to crash an application that bundles the dcraw code. (CVE-2018-19568)

  - 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)

  - An error within the LibRaw::unpack() function (src/libraw_cxx.cpp) in LibRaw versions prior to 0.18.7
    can be exploited to trigger a NULL pointer dereference. (CVE-2018-5801)

  - A boundary error within the quicktake_100_load_raw() function (internal/dcraw_common.cpp) in LibRaw
    versions prior to 0.18.8 can be exploited to cause a stack-based buffer overflow and subsequently cause a
    crash. (CVE-2018-5805)

  - An error within the leaf_hdr_load_raw() function (internal/dcraw_common.cpp) in LibRaw versions prior to
    0.18.8 can be exploited to trigger a NULL pointer dereference. (CVE-2018-5806)

  - There is an integer overflow vulnerability in dcraw. When the victim runs dcraw with a maliciously crafted
    X3F input image, arbitrary code may be executed in the victim's system. (CVE-2021-3624)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
