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.

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.

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.

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.

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.

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.

Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A heap buffer overflow was found in Exiv2 versions v0.27.3 and earlier. The heap overflow is triggered when Exiv2 is used to write metadata into 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. Note that this bug is only triggered when writing the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as insert. The bug is fixed in version v0.27.4.

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 0.27.99.0 has a heap-based buffer over-read in Exiv2::RafImage::readMetadata() in rafimage.cpp.

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.

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.

An integer overflow in CrwMap::encode0x1810 of Exiv2 0.27.3 allows attackers to trigger a heap-based buffer overflow and cause a denial of service (DOS) via crafted metadata.

There is an illegal address access in the extendaliastable function in localealias.c of Exiv2 0.26. A crafted input will lead to remote denial of service.

There is a Mismatched Memory Management Routines vulnerability in the Exiv2::FileIo::seek function of Exiv2 0.26 that will lead to a remote denial of service attack (heap memory corruption) via crafted input.

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.

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.
