Exiv2: Out-of-bounds read in CrwMap::decode0x0805

Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. Prior to version 0.28.8, an out-of-bounds read was found. The vulnerability is in the CRW image parser. This issue has been patched in version 0.28.8.

Exiv2: Integer Underflow in LoaderNative::getData() Causes Heap Buffer Overflow

Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. Prior to version 0.28.8, an out-of-bounds read was found in Exiv2. The vulnerability is in the preview component, which is only triggered when running Exiv2 with an extra command line argument, like -pp. The out-of-bounds read is at a 4GB offset, which usually causes Exiv2 to crash. This issue has been patched in version 0.28.8.

Exiv2: Uncaught exception - cannot create std::vector larger than max_size()

Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. Prior to version 0.28.8, an uncaught exception was found in Exiv2. The vulnerability is in the preview component, which is only triggered when running Exiv2 with an extra command line argument, like -pp. Due to an integer overflow, the code attempts to create a huge std::vector, which causes Exiv2 to crash with an uncaught exception. This issue has been patched in version 0.28.8.

Exiv2 has quadratic performance in ICC profile parsing in JpegBase::readMetadata

Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. A denial-of-service was found in Exiv2 version 0.28.5: a quadratic algorithm in the ICC profile parsing code in jpegBase::readMetadata() can cause Exiv2 to run for a long time. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted jpg image file. The bug is fixed in version 0.28.6.

Exiv2 Segmentation Faults in Exiv2::EpsImage::writeMetadata() via crafted EPS file

Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. An out-of-bounds read was found in Exiv2 versions 0.28.5 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. The bug is fixed in version 0.28.6.

Out-of-bounds read in QuickTimeVideo::NikonTagsDecoder in Exiv2

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 version v0.28.1. The vulnerable function, `QuickTimeVideo::NikonTagsDecoder`, was new in v0.28.0, so Exiv2 versions before v0.28 are _not_ affected. The out-of-bounds read is triggered when Exiv2 is used to read the metadata of a crafted video file. In most cases this out of bounds read will result in a crash. This bug is fixed in version v0.28.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Denial of service due to unbounded recursion in QuickTimeVideo::multipleEntriesDecoder in Exiv2

Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A denial-of-service was found in Exiv2 version v0.28.1: an unbounded recursion can cause Exiv2 to crash by exhausting the stack. The vulnerable function, `QuickTimeVideo::multipleEntriesDecoder`, was new in v0.28.0, so Exiv2 versions before v0.28 are _not_ affected. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted video file. This bug is fixed in version v0.28.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.

CVE-2020-18831

Buffer Overflow vulnerability in tEXtToDataBuf function in pngimage.cpp in Exiv2 0.27.1 allows remote attackers to cause a denial of service and other unspecified impacts via use of crafted file.

• Update to 0.27.2-6

CVE-2020-18774

A float point exception in the printLong function in tags_int.cpp of Exiv2 0.27.99.0 allows attackers to cause a denial of service (DOS) via a crafted tif file.

CVE-2020-18773

An invalid memory access in the decode function in iptc.cpp of Exiv2 0.27.99.0 allows attackers to cause a denial of service (DOS) via a crafted tif file.

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.

• Update to 0.27.2-6

CVE-2020-18898

A stack exhaustion issue in the printIFDStructure function of Exiv2 0.27 allows remote attackers to cause a denial of service (DOS) via a crafted file.

CVE-2020-18899

An uncontrolled memory allocation in DataBufdata(subBox.length-sizeof(box)) function of Exiv2 0.27 allows attackers to cause a denial of service (DOS) via a crafted input.

• Update to 0.27.2-6

Denial of service due to infinite loop in JpegBase::printStructure (#2)

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.

• Update to 0.27.5-1

Denial of service due to infinite loop in JpegBase::printStructure (#1)

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.

Denial of service due to infinite loop in Image::printIFDStructure

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
