Уязвимость функции jpegBase::readMetadata() библиотеки и утилиты командной строки для управления метаданными изображений Exiv2, позволяющая нарушителю вызвать отказ в обслуживании

Уязвимость команд библиотеки для управления метаданными медиафайлов Exiv2, связанная с чтением за границами буфера в памяти, позволяющая нарушителю вызвать отказ в обслуживании

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 read was found in Exiv2 versions 0.28.5 and earlier. The out-of-bounds read is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service by crashing Exiv2, 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. The bug is fixed in version 0.28.6.

Exiv2 is a C++ library and a command-line utility to read, write, delete and modify Exif, IPTC, XMP and ICC image metadata. A denial-of-service was found in Exiv2 version 0.28.5: a quadratic algorithm in the ICC profile parsing code in jpegBase::readMetadata() can cause Exiv2 to run for a long time. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted jpg image file. The bug is fixed in version 0.28.6.
