The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4941-1 advisory.

  - poppler since version 0.17.3 has been vulnerable to NULL pointer dereference in pdfunite triggered by     specially crafted documents. (CVE-2017-7511)

  - In Poppler 0.72.0, PDFDoc::setup in PDFDoc.cc allows attackers to cause a denial-of-service (application     crash caused by Object.h SIGABRT, because of a wrong return value from PDFDoc::setup) by crafting a PDF     file in which an xref data structure is mishandled during extractPDFSubtype processing. (CVE-2018-20662)

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

  - The function GfxImageColorMap::getGray in GfxState.cc in Poppler 0.54.0 allows remote attackers to cause a     denial of service (stack-based buffer over-read and application crash) via a crafted PDF document, related     to missing color-map validation in ImageOutputDev.cc. (CVE-2017-9865)

  - FontInfoScanner::scanFonts in FontInfo.cc in Poppler 0.75.0 has infinite recursion, leading to a call to     the error function in Error.cc. (CVE-2019-11026)

  - 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)

  - In Poppler 22.07.0, PDFDoc::savePageAs in PDFDoc.c callows attackers to cause a denial-of-service     (application crashes with SIGABRT) by crafting a PDF file in which the xref data structure is mishandled     in getCatalog processing. Note that this vulnerability is caused by the incomplete patch of     CVE-2018-20662. (CVE-2022-37050)

  - An issue was discovered in Poppler 22.07.0. There is a reachable abort which leads to denial of service     because the main function in pdfunite.cc lacks a stream check before saving an embedded file.
    (CVE-2022-37051)

  - A reachable Object::getString assertion in Poppler 22.07.0 allows attackers to cause a denial of service     due to a failure in markObject. (CVE-2022-37052)

  - An issue was discovered in Poppler 22.08.0. There is a reachable assertion in Object.h, will lead to     denial of service because PDFDoc::replacePageDict in PDFDoc.cc lacks a stream check before saving an     embedded file. (CVE-2022-38349)

  - Poppler prior to and including 22.08.0 contains an integer overflow in the JBIG2 decoder     (JBIG2Stream::readTextRegionSeg() in JBIGStream.cc). Processing a specially crafted PDF file or JBIG2     image could lead to a crash or the execution of arbitrary code. This is similar to the vulnerability     described by CVE-2022-38171 in Xpdf. (CVE-2022-38784)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

  - poppler through version 0.55.0 is vulnerable to an     uncontrolled recursion in pdfunite resulting into     potential denial-of-service.(CVE-2017-7515)

  - 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)

  - In Poppler 0.54.0, a memory leak vulnerability was     found in the function gmalloc in gmem.cc, which allows     attackers to cause a denial of service via a crafted     file.(CVE-2017-9406)

  - In Poppler 0.54.0, a memory leak vulnerability was     found in the function Object::initArray in Object.cc,     which allows attackers to cause a denial of service via     a crafted file.(CVE-2017-9408)

  - The JPXStream::init function in Poppler 0.78.0 and     earlier doesn't check for negative values of stream     length, leading to an Integer Overflow, thereby making     it possible to allocate a large memory chunk on the     heap, with a size controlled by an attacker, as     demonstrated by pdftocairo.(CVE-2019-9959)
