Exiv2 0.27.99.0 has a global buffer over-read in Exiv2::Internal::Nikon1MakerNote::print0x0088 in nikonmnint.cpp which can result in an information leak.

A buffer overflow vulnerability in the Databuf function in types.cpp of Exiv2 v0.27.1 leads to a denial of service (DOS).

In Exiv2 0.27.99.0, there is an out-of-bounds read in Exiv2::MrwImage::readMetadata() in mrwimage.cpp. It could result in denial of service.

Exiv2::PngImage::readMetadata() in pngimage.cpp in Exiv2 0.27.99.0 allows attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file.

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

It was discovered that Exiv2 incorrectly handled certain files. An attacker could possibly use this issue to cause a denial of service.
