An issue was discovered in Exiv2 0.27. There is infinite recursion at BigTiffImage::printIFD in the file bigtiffimage.cpp. This can be triggered by a crafted file. It allows an attacker to cause Denial of Service (Segmentation fault) or possibly have unspecified other impact.

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.
There is a Segmentation fault in the XmpParser::terminate() function in Exiv2 0.26, related to an exit call. A Crafted input will lead to a remote denial of service attack.
There is a heap-based buffer overflow in the Image::printIFDStructure function of image.cpp in Exiv2 0.26. A Crafted input will lead to a remote denial of service attack.
There is a heap-based buffer overflow in basicio.cpp of Exiv2 0.26. The vulnerability causes an out-of-bounds write in Exiv2::Image::printIFDStructure(), which may lead to remote denial of service or possibly unspecified other impact.
There is an infinite loop in the Exiv2::Image::printIFDStructure function of image.cpp in Exiv2 0.26. A crafted input will lead to a remote denial of service attack.
There is a heap-based buffer over-read in libexiv2 in Exiv2 0.26 that is triggered in the Exiv2::Image::io function in image.cpp. It will lead to remote denial of service.
Exiv2 0.26 contains a heap buffer overflow in tiff parser
There is an invalid free in the Action::TaskFactory::cleanup function of actions.cpp in Exiv2 0.26. A crafted input will lead to a remote denial of service attack.
Exiv2 0.16 allows user-assisted remote attackers to cause a denial of service (divide-by-zero and application crash) via a zero value in Nikon lens information in the metadata of an image, related to "pretty printing" and the RationalValue::toLong function.
exiv2 0.26 contains a Stack out of bounds read in webp parser
There is an illegal address access in the extendaliastable function in localealias.c of Exiv2 0.26. A crafted input will lead to remote denial of service.
There is a Mismatched Memory Management Routines vulnerability in the Exiv2::FileIo::seek function of Exiv2 0.26 that will lead to a remote denial of service attack (heap memory corruption) via crafted input.
A flaw was found in Exiv2 0.26. A heap-based buffer over-read in WebPImage::decodeChunks in webpimage.cpp.

Exiv2::Image::byteSwap2 in image.cpp in Exiv2 0.26 has a heap-based buffer over-read.
In Exiv2 before v0.27.2, there is an integer overflow vulnerability in the WebPImage::getHeaderOffset function in webpimage.cpp. It can lead to a buffer overflow vulnerability and a crash.
Exiv2 0.27.99.0 has a heap-based buffer over-read in Exiv2::RafImage::readMetadata() in rafimage.cpp.
A float point exception in the printLong function in tagsint.cpp of Exiv2 0.27.99.0 allows attackers to cause a denial of service (DOS) via a crafted tif file.
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.
In Jp2Image::readMetadata() in jp2image.cpp in Exiv2 0.27.2, an input file can result in an infinite loop and hang, with high CPU consumption. Remote attackers could leverage this vulnerability to cause a denial of service via a crafted file.

Upstream Fix:
https://github.com/Exiv2/exiv2/commit/a82098f4f90cd86297131b5663c3dec6a34470e8
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 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.

A flaw was found in Exiv2 0.26. There is a integer underflow, leading to a heap-based buffer over-read, in the Exiv2::IptcData::printStructure function in iptc.cpp. Remote attackers can exploit this vulnerability to cause a denial of service via a crafted TIFF file or, possibly, disclose memory data.

In Exiv2 0.26, an out-of-bounds read in IptcData::printStructure in iptc.cpp could result in a crash or information leak, due to use of the untrusted len value without any check.
