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 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. Prior to version 0.28.8, an out-of-bounds read was found. The vulnerability is in the CRW image parser. This issue has been patched in version 0.28.8.

In Exiv2 0.26, an out-of-bounds read in IptcData::printStructure in iptc.c could result in a crash or information leak, related to the "== 0x1c" case.

In Exiv2 0.26, there is a heap-based buffer over-read in the Exiv2::Image::byteSwap4 function in image.cpp. Remote attackers can exploit this vulnerability to disclose memory data or cause a denial of service via a crafted TIFF file.

In Exiv2 0.26, there is an out-of-bounds read in Exiv2::Internal::binaryToString in image.cpp. It could result in denial of service or information disclosure.

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.

Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. Prior to version 0.28.8, an out-of-bounds read was found in Exiv2. The vulnerability is in the preview component, which is only triggered when running Exiv2 with an extra command line argument, like -pp. The out-of-bounds read is at a 4GB offset, which usually causes Exiv2 to crash. This issue has been patched in version 0.28.8.

There is an invalid free in Image::printIFDStructure that leads to a Segmentation fault in Exiv2 0.26. A crafted input will lead to a remote denial of service attack.

Integer overflow in exif.cpp in exiv2 library allows context-dependent attackers to execute arbitrary code via a crafted EXIF file that triggers a heap-based buffer overflow.

A flaw was found in Exiv2 0.26. The CiffDirectory::readDirectory() function at crwimageint.cpp has an excessive stack consumption due to a recursive function, leading to Denial of service.

A CiffDirectory::readDirectory integer overflow and out-of-bounds read in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (SIGSEGV) via a crafted CRW image file.

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

An issue was discovered in Exiv2 0.26. readMetadata in jp2image.cpp allows remote attackers to cause a denial of service (SIGABRT) by triggering an incorrect Safe::add call.

A flaw was found in Exiv2 0.26. A heap-based buffer over-read in Exiv2::IptcParser::decode in iptc.cpp (called from psdimage.cpp in the PSD image reader). This could lead to a denial of service caused by an integer overflow via a crafted PSD image file.

Exiv2 0.27.2 allows attackers to trigger a crash in Exiv2::getULong in types.cpp when called from Exiv2::Internal::CiffDirectory::readDirectory in crwimageint.cpp, because there is no validation of the relationship of the total size to the offset and size.

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.

An issue was discovered in Exiv2 0.26. When the data structure of the structure ifd is incorrect, the program assigns pValue to 0x0, and the value of pValue() is 0x0. TiffImageEntry::doWriteImage will use the value of pValue() to cause a segmentation fault. To exploit this vulnerability, someone must open a crafted tiff file.

A flaw was found in Exiv2 0.26, the Exiv2::Internal::printCsLensFFFF function in canonmnint.cpp allows remote attackers to cause a denial of service (invalid memory access) via a crafted file.
