ALSA-2021:4173 — Moderate: exiv2 security, bug fix, and enhancement update

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)

OESA-2021-1451 — exiv2 security update

Affected: openEuler:20.03-LTS-SP1: exiv2, openEuler:20.03-LTS-SP2: exiv2

Exiv2 is a Cross-platform C++ library and a command line utility to manage image metadata. It provides fast and easy read and write access to the Exif, IPTC and XMP metadata and the ICC Profile embedded within digital images in various formats. Security Fix(es): An integer overflow in Exiv2 through 0.27.1 allows an attacker to cause a denial of service (SIGSEGV) via a crafted PNG image file, because PngImage::readMetadata mishandles a zero value for iccOffset.(CVE-2019-13108) There is an out-of-bounds read in Exiv2::MrwImage::readMetadata in mrwimage.cpp in Exiv2 through 0.27.2.(CVE-2019-13504) Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A null pointer dereference was found in Exiv2 versions v0.27.4 and earlier. The null pointer dereference is triggered when Exiv2 is used to print the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when printing the interpreted (translated) data, which is a less frequently used Exiv2 operation that requires an extra command line option (`-p t` or `-P t`). The bug is fixed in version v0.27.5.(CVE-2021-37616) Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. A null pointer dereference was found in Exi…
