New upstream bugfix and security release.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

It was discovered that there was an integer overflow vulnerability in exiv2, a tool to manipulate images containing (eg.) EXIF metadata.

This could have resulted in a denial of service via a specially- crafted file. 

For Debian 8 'Jessie', this issue has been fixed in exiv2 version 0.24-4.1+deb8u4.

We recommend that you upgrade your exiv2 packages.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3265 advisory.

    This update fixes a number of memory access violations and other input     validation failures that can be triggered by passing specially crafted files to     exiv2.

    CVE-2017-11591

        There is a Floating point exception in the Exiv2::ValueType function that         will lead to a remote denial of service attack via crafted input.

    CVE-2017-14859

        An Invalid memory address dereference was discovered in         Exiv2::StringValueBase::read in value.cpp. 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::DataValue::read in value.cpp. The vulnerability causes a         segmentation fault and application crash, which leads to denial of service.

    CVE-2017-14864

        An Invalid memory address dereference was discovered in Exiv2::getULong in         types.cpp. The vulnerability causes a segmentation fault and application         crash, which leads to denial of service.

    CVE-2017-17669

        There is a heap-based buffer over-read in the         Exiv2::Internal::PngChunk::keyTXTChunk function of pngchunk_int.cpp. A         crafted PNG file will lead to a remote denial of service attack.

    CVE-2017-18005

        Exiv2 has a Null Pointer Dereference in the Exiv2::DataValue::toLong         function in value.cpp, related to crafted metadata in a TIFF file.

    CVE-2018-8976

        jpgimage.cpp allows remote attackers to cause a denial of service         (image.cpp Exiv2::Internal::stringFormat out-of-bounds read) via a crafted         file.

    CVE-2018-17581

        CiffDirectory::readDirectory() at crwimage_int.cpp has excessive stack         consumption due to a recursive function, leading to Denial of service.

    CVE-2018-19107

        Exiv2::IptcParser::decode in iptc.cpp (called from psdimage.cpp in the PSD         image reader) may suffer from a denial of service (heap-based buffer         over-read) caused by an integer overflow via a crafted PSD image file.

    CVE-2018-19108

        Exiv2::PsdImage::readMetadata in psdimage.cpp in the PSD image reader may         suffer from a denial of service (infinite loop) caused by an integer         overflow via a crafted PSD image file.

    CVE-2018-19535

        PngChunk::readRawProfile in pngchunk_int.cpp may cause a denial of service         (application crash due to a heap-based buffer over-read) via a crafted PNG         file.

    CVE-2018-20097

        There is a SEGV in Exiv2::Internal::TiffParserWorker::findPrimaryGroups of         tiffimage_int.cpp. A crafted input will lead to a remote denial of service         attack.

    CVE-2019-13110

        A CiffDirectory::readDirectory integer overflow and out-of-bounds read         allows an attacker to cause a denial of service (SIGSEGV) via a crafted CRW         image file.

    CVE-2019-13112

        A PngChunk::parseChunkContent uncontrolled memory allocation allows an         attacker to cause a denial of service (crash due to an std::bad_alloc         exception) via a crafted PNG image file.

    CVE-2019-13114

        http.c allows a malicious http server to cause a denial of service (crash         due to a NULL pointer dereference) by returning a crafted response that         lacks a space character.

    CVE-2019-13504

        There is an out-of-bounds read in Exiv2::MrwImage::readMetadata in         mrwimage.cpp.

    CVE-2019-14369

        Exiv2::PngImage::readMetadata() in pngimage.cpp allows attackers to cause a         denial of service (heap-based buffer over- read) via a crafted image file.

    CVE-2019-14370

        There is an out-of-bounds read in Exiv2::MrwImage::readMetadata() in         mrwimage.cpp. It could result in denial of service.

    CVE-2019-17402

        Exiv2 allows attackers to trigger a crash in Exiv2::getULong in types.cpp         when called from Exiv2::Internal::CiffDirectory::readDirectory in         crwimage_int.cpp, because there is no validation of the relationship of the         total size to the offset and size.

    CVE-2020-18771

        Exiv2 has a global buffer over-read in         Exiv2::Internal::Nikon1MakerNote::print0x0088 in nikonmn_int.cpp which can         result in an information leak.

    CVE-2021-29458

        An out-of-bounds read was found in Exiv2. The out-of- bounds read is         triggered when Exiv2 is used to write metadata into a crafted image file.
        An attacker could potentially exploit the vulnerability to cause a denial         of service by crashing Exiv2, if they can trick the victim into running         Exiv2 on a crafted image file. Note that this bug is only triggered when         writing the metadata, which is a less frequently used Exiv2 operation than         reading the metadata. For example, to trigger the bug in the Exiv2         command-line application, you need to add an extra command-line argument         such as insert.

    CVE-2021-32815

        The assertion         failure is triggered when Exiv2 is used to modify the metadata of a         crafted image file. An attacker could potentially exploit the         vulnerability to cause a denial of service, if they can trick the         victim into running Exiv2 on a crafted image file. Note that this bug         is only triggered when modifying the metadata, which is a less         frequently used Exiv2 operation than reading the metadata. For         example, to trigger the bug in the Exiv2 command-line application, you         need to add an extra command-line argument such as `fi`.

    CVE-2021-34334

        An infinite loop is triggered when Exiv2 is used to read the metadata of a         crafted image file. An attacker could potentially exploit the vulnerability         to cause a denial of service, if they can trick the victim into running         Exiv2 on a crafted image file.

    CVE-2021-37620

        An out-of-bounds read is triggered when Exiv2 is used to read the metadata         of a crafted image file. An attacker could potentially exploit the         vulnerability to cause a denial of service, if they can trick the victim         into running Exiv2 on a crafted image file.

    CVE-2021-37621

        An infinite loop is triggered when Exiv2 is used to print the metadata of a         crafted image file. An attacker could potentially exploit the vulnerability         to cause a denial of service, if they can trick the victim into running         Exiv2 on a crafted image file. Note that this bug is only triggered when         printing the image ICC profile, which is a less frequently used Exiv2         operation that requires an extra command line option (`-p C`).

    CVE-2021-37622

        An infinite loop is triggered when Exiv2 is used to modify the metadata of         a crafted image file. An attacker could potentially exploit the         vulnerability to cause a denial of service, if they can trick the victim         into running Exiv2 on a crafted image file. Note that this bug is only         triggered when deleting the IPTC data, which is a less frequently used         Exiv2 operation that requires an extra command line option (`-d I rm`).

    For Debian 10 buster, these problems have been fixed in version     0.25-4+deb10u4.

    We recommend that you upgrade your exiv2 packages.
