exiv2: Out-of-bounds read in Exiv2::Jp2Image::encodeJp2Header

CVE-2021-29470 [MEDIUM] CWE-125 exiv2: Out-of-bounds read in Exiv2::Jp2Image::encodeJp2Header exiv2: Out-of-bounds read in Exiv2::Jp2Image::encodeJp2Header 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 i

CVE-2021-29470 [MEDIUM] CWE-125 Out-of-bounds read in Exiv2::Jp2Image::encodeJp2Header Out-of-bounds read in Exiv2::Jp2Image::encodeJp2Header FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability? One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
