Published Nov 9, 2021 · Updated Feb 4, 2026

Ecosystem: Rocky Linux

Summary

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)
