Exiv2::ul2Data in types.cpp in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-based buffer overflow) via a crafted image file.

Exiv2::d2Data in types.cpp in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-based buffer overflow) via a crafted image file.

Exiv2::Internal::PngChunk::parseTXTChunk in Exiv2 v0.26 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted image file, a different vulnerability than CVE-2018-10999.

samples/geotag.cpp in the example code of Exiv2 0.26 misuses the realpath function on POSIX platforms (other than Apple platforms) where glibc is not used, possibly leading to a buffer overflow.

Exiv2 0.26 has a heap-based buffer over-read in WebPImage::decodeChunks in webpimage.cpp.

Exiv2 0.26 has an integer overflow in the LoaderExifJpeg class in preview.cpp, leading to an out-of-bounds read in Exiv2::MemIo::read in basicio.cpp.

Exiv2 0.26 has integer overflows in LoaderTiff::getData() in preview.cpp, leading to an out-of-bounds read in Exiv2::ValueType::setDataArea in value.hpp.

Exiv2 0.26 has a heap-based buffer overflow in getData in preview.cpp.

In Exiv2 0.26, the Exiv2::PngImage::printStructure function in pngimage.cpp allows remote attackers to cause an information leak via a crafted file.

An issue was discovered in Exiv2 0.26. The Exiv2::Internal::PngChunk::parseTXTChunk function has a heap-based buffer over-read.
