The remote NewStart CGSL host, running version MAIN 6.02, has exiv2 packages installed that are affected by multiple vulnerabilities:
Exiv2 0.27.2 allows attackers to trigger a crash in Exiv2::getULong in types.cpp when called from Exiv2::Internal::CiffDirectory::readDirectory in crwimage_int.cpp, because there is no validation of the relationship of the total size to the offset and size. (CVE-2019-17402)
A flaw was found in Exiv2 in versions before and including 0.27.4-RC1. Improper input validation of the rawData.size property in Jp2Image::readMetadata() in jp2image.cpp can lead to a heap-based buffer overflow via a crafted JPG image containing malicious EXIF data. (CVE-2021-3482)
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. (CVE-2021-29457)
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 versions v0.27.3 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. 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. (CVE-2021-29458, CVE-2021-29470)
