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.

There is a heap-based buffer over-read in the Image::printIFDStructure function in image.cpp in Exiv2 0.26. A Crafted input will lead to a remote denial of service attack.

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 policy](https://github.com/Exiv2/exiv2/security/policy) for information about Exiv2 security.

There is an out-of-bounds read in Exiv2::MrwImage::readMetadata in mrwimage.cpp in Exiv2 through 0.27.2.

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.

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.
