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
in Exiv2 0.26 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 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::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-2017-14864
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-2017-17669
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-2017-18005
Exiv2 0.26 has a Null Pointer Dereference in the
Exiv2::DataValue::toLong function in value.cpp, related to crafted
metadata in a TIFF file.

CVE-2018-17581
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-2018-19107
In Exiv2 0.26, 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
In Exiv2 0.26, 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
In Exiv2 0.26 and previous versions, 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 in Exiv2 0.27-RC3. A crafted input will lead to a
remote denial of service attack.

CVE-2018-8976
In Exiv2 0.26, 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-2019-13110
A CiffDirectory::readDirectory integer overflow and out-of-bounds read
in Exiv2 through 0.27.1 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 in Exiv2
through 0.27.1 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 in Exiv2 through 0.27.1 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 in Exiv2 through 0.27.2.

CVE-2019-14369
Exiv2::PngImage::readMetadata() in pngimage.cpp in Exiv2 0.27.99.0
allows attackers to cause a denial of service (heap-based buffer over-
read) via a crafted image file.

CVE-2019-14370
In Exiv2 0.27.99.0, 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 0.27.2 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 0.27.99.0 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
Exiv2 is a command-line utility and C++ library for reading, writing,
deleting, and modifying the metadata of image files. An out-of-bounds
read was found in Exiv2 versions v0.27.3 and earlier. 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. The bug is
fixed in version v0.27.4.

CVE-2021-32815
Exiv2 is a command-line utility and C++ library for reading, writing,
deleting, and modifying the metadata of image files. 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`. ### Patches
The bug is fixed in version v0.27.5. ### References Regression test
and bug fix: #1739 ### For more information Please see our [security

CVE-2021-34334
Exiv2 is a command-line utility and C++ library for reading, writing,
deleting, and modifying the metadata of image files. 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. The bug is fixed in version v0.27.5.

CVE-2021-37620
Exiv2 is a command-line utility and C++ library for reading, writing,
deleting, and modifying the metadata of image files. An out-of-bounds
read was found in Exiv2 versions v0.27.4 and earlier. The 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. The bug is fixed in
version v0.27.5.

CVE-2021-37621
Exiv2 is a command-line utility and C++ library for reading, writing,
deleting, and modifying the metadata of image files. An infinite loop
was found in Exiv2 versions v0.27.4 and earlier. The 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`). The bug
is fixed in version v0.27.5.

CVE-2021-37622
Exiv2 is a command-line utility and C++ library for reading, writing,
deleting, and modifying the metadata of image files. An infinite loop
was found in Exiv2 versions v0.27.4 and earlier. The 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`). The
bug is fixed in version v0.27.5.
