The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:2907-1 advisory.

  - The FoFiType1C::cvtGlyph function in fofi/FoFiType1C.cc in Poppler through 0.64.0 allows remote attackers     to cause a denial of service (infinite recursion) via a crafted PDF file, as demonstrated by pdftops.
    (CVE-2017-18267)

  - Poppler through 0.62 contains an out of bounds read vulnerability due to an incorrect memory access that     is not mapped in its memory space, as demonstrated by pdfunite. This can result in memory corruption and     denial of service. This may be exploitable when a victim opens a specially crafted PDF file.
    (CVE-2018-13988)

  - In Poppler 0.68.0, the Parser::getObj() function in Parser.cc may cause infinite recursion via a crafted     file. A remote attacker can leverage this for a DoS attack. (CVE-2018-16646)

  - An issue was discovered in Poppler 0.71.0. There is a memory leak in GfxColorSpace::setDisplayProfile in     GfxState.cc, as demonstrated by pdftocairo. (CVE-2018-18897)

  - An issue was discovered in Poppler 0.71.0. There is a reachable abort in Object.h, will lead to denial of     service because EmbFile::save2 in FileSpec.cc lacks a stream check before saving an embedded file.
    (CVE-2018-19058)

  - An issue was discovered in Poppler 0.71.0. There is a out-of-bounds read in EmbFile::save2 in FileSpec.cc,     will lead to denial of service, as demonstrated by utils/pdfdetach.cc not validating embedded files before     save attempts. (CVE-2018-19059)

  - An issue was discovered in Poppler 0.71.0. There is a NULL pointer dereference in goo/GooString.h, will     lead to denial of service, as demonstrated by utils/pdfdetach.cc not validating a filename of an embedded     file before constructing a save path. (CVE-2018-19060)

  - Poppler before 0.70.0 has a NULL pointer dereference in _poppler_attachment_new when called from     poppler_annot_file_attachment_get_attachment. (CVE-2018-19149)

  - XRef::getEntry in XRef.cc in Poppler 0.72.0 mishandles unallocated XRef entries, which allows remote     attackers to cause a denial of service (NULL pointer dereference) via a crafted PDF document, when     XRefEntry::setFlag in XRef.h is called from Parser::makeStream in Parser.cc. (CVE-2018-20481)

  - A reachable Object::dictLookup assertion in Poppler 0.72.0 allows attackers to cause a denial of service     due to the lack of a check for the dict data type, as demonstrated by use of the FileSpec class (in     FileSpec.cc) in pdfdetach. (CVE-2018-20650)

  - Poppler before 0.66.0 has an integer overflow in Parser::makeStream in Parser.cc. (CVE-2018-21009)

  - In Poppler through 0.76.1, there is a heap-based buffer over-read in JPXStream::init in JPEG2000Stream.cc     via data with inconsistent heights or widths. (CVE-2019-12293)

  - In Poppler 0.73.0, a heap-based buffer over-read (due to an integer signedness error in the XRef::getEntry     function in XRef.cc) allows remote attackers to cause a denial of service (application crash) or possibly     have unspecified other impact via a crafted PDF document, as demonstrated by pdftocairo. (CVE-2019-7310)

  - A logic error in the Hints::Hints function of Poppler v22.03.0 allows attackers to cause a Denial of     Service (DoS) via a crafted PDF file. (CVE-2022-27337)

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