An issue was discovered in Exiv2 0.27. There is infinite recursion at Exiv2::Image::printTiffStructure in the file image.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 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.
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.
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 write was found in Exiv2 version v0.28.0. The vulnerable function, BmffImage::brotliUncompress, is new in v0.28.0, so earlier versions of Exiv2 are not affected. The out-of-bounds write is triggered when Exiv2 is used to read the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to gain code execution, if they can trick the victim into running Exiv2 on a crafted image file. This bug is fixed in version v0.28.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
A flaw was found in Exiv2 0.26. The samples/geotag.cpp in the example code misuses the realpath function on POSIX platforms (other than Apple platforms) where glibc is not used, possibly leading to a buffer overflow.

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 v0.28.2. The vulnerability is in the parser for the ASF video format, which was a new feature in v0.28.0. The out-of-bounds read is triggered when Exiv2 is used to read the metadata of a crafted video file. The bug is fixed in version v0.28.3.
