The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3852-1 advisory.
There is a Floating point exception in the Exiv2::ValueType function in Exiv2 0.26 that will lead to a remote denial of service attack via crafted input. (CVE-2017-11591)
There is a reachable assertion in the Internal::TiffReader::visitDirectory function in tiffvisitor.cpp of Exiv2 0.26 that will lead to a remote denial of service attack via crafted input. (CVE-2017-11683)
An Invalid memory address dereference was discovered in Exiv2::StringValueBase::read in value.cpp in Exiv2 0.26. The vulnerability causes a segmentation fault and application crash, which leads to denial of service. (CVE-2017-14859)
An Invalid memory address dereference was discovered in Exiv2::DataValue::read in value.cpp in Exiv2 0.26.
The vulnerability causes a segmentation fault and application crash, which leads to denial of service.
(CVE-2017-14862)
An Invalid memory address dereference was discovered in Exiv2::getULong in types.cpp in Exiv2 0.26. The vulnerability causes a segmentation fault and application crash, which leads to denial of service.
(CVE-2017-14864)
There is a heap-based buffer over-read in the Exiv2::Internal::PngChunk::keyTXTChunk function of pngchunk_int.cpp in Exiv2 0.26. A crafted PNG file will lead to a remote denial of service attack.
(CVE-2017-17669)
An issue was discovered in Exiv2 0.26. When the data structure of the structure ifd is incorrect, the program assigns pValue_ to 0x0, and the value of pValue() is 0x0. TiffImageEntry::doWriteImage will use the value of pValue() to cause a segmentation fault. To exploit this vulnerability, someone must open a crafted tiff file. (CVE-2017-9239)
Exiv2::Internal::PngChunk::parseTXTChunk in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file, a different vulnerability than CVE-2018-10999. (CVE-2018-16336)
CiffDirectory::readDirectory() at crwimage_int.cpp in Exiv2 0.26 has excessive stack consumption due to a recursive function, leading to Denial of service. (CVE-2018-17581)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
