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.
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.
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.
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.

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.

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.
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 Exiv2::Jp2Image::encodeJp2Header of jp2image.cpp in Exiv2 0.27-RC3. A crafted input will lead to a denial of service attack.
