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.
