Affected: AlmaLinux:8: exiv2, AlmaLinux:8: exiv2-devel, AlmaLinux:8: exiv2-doc, AlmaLinux:8: exiv2-libs

Exiv2 is a C++ library to access image metadata, supporting read and write access to the Exif, IPTC and XMP metadata, Exif MakerNote support, extract and delete methods for Exif thumbnails, classes to access Ifd, and support for various image formats.

The following packages have been upgraded to a later upstream version: exiv2 (0.27.4). (BZ#1989860)

Security Fix(es):

* exiv2: Heap-based buffer overflow in Jp2Image::readMetadata() (CVE-2021-3482)

* exiv2: Heap-based buffer overflow in Exiv2::Jp2Image::doWriteMetadata (CVE-2021-29457)

* exiv2: Out-of-bounds read in Exiv2::Internal::CrwMap::encode (CVE-2021-29458)

* exiv2: Heap-based buffer overflow in Exiv2::Jp2Image::encodeJp2Header (CVE-2021-29464)

* exiv2: Out-of-bounds read in Exiv2::Jp2Image::encodeJp2Header (CVE-2021-29470)

* exiv2: Out-of-bounds read in Exiv2::Jp2Image::doWriteMetadata (CVE-2021-29473)

* exiv2: Integer overflow in CrwMap:encode0x1810 leading to heap-based buffer overflow and DoS (CVE-2021-31292)

* exiv2: Out-of-bounds read in Exiv2::WebPImage::doWriteMetadata (CVE-2021-29463)

* exiv2: Use of uninitialized memory in isWebPType() may lead to information leak (CVE-2021-29623)

* exiv2: DoS due to quadratic complexity in ProcessUTF8Portion (CVE-2021-32617)

* exiv2: Out-of-bounds read in Exiv2::Jp2Image::printStructure (CVE-2021-37618)

* exiv2: Out-of-bounds read in Exiv2::Jp2Image::encodeJp2Header (CVE-2021-37619)

Affected: CleanStart: exiv2

Security vulnerability affects the exiv2 package. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files.

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.
