ALSA-2020:1577 — Moderate: exiv2 security, bug fix, and enhancement update

2026-10-03T06:11:41.818583+00:00

Affected: AlmaLinux:8: exiv2-devel, AlmaLinux:8: exiv2-doc, AlmaLinux:8: gegl, AlmaLinux:8: gnome-color-manager, AlmaLinux:8: libgexiv2, AlmaLinux:8: libgexiv2-devel

The exiv2 packages provide a command line utility which can display and manipulate image metadata such as EXIF, LPTC, and JPEG comments.

The following packages have been upgraded to a later upstream version: exiv2 (0.27.2). (BZ#1651917)

Security Fix(es):

* exiv2: infinite loop and hang in Jp2Image::readMetadata() in jp2image.cpp could lead to DoS (CVE-2019-20421)

* exiv2: null pointer dereference in the Exiv2::DataValue::toLong function in value.cpp (CVE-2017-18005)

* exiv2: Excessive memory allocation in Exiv2::Jp2Image::readMetadata function in jp2image.cpp (CVE-2018-4868)

* exiv2: assertion failure in BigTiffImage::readData in bigtiffimage.cpp (CVE-2018-9303)

* exiv2: divide by zero in BigTiffImage::printIFD in bigtiffimage.cpp (CVE-2018-9304)

* exiv2: out of bounds read in IptcData::printStructure in iptc.c (CVE-2018-9305)

* exiv2: OOB read in pngimage.cpp:tEXtToDataBuf() allows for crash via crafted file (CVE-2018-10772)

* exiv2: information leak via a crafted file (CVE-2018-11037)

* exiv2: buffer overflow in samples/geotag.cpp (CVE-2018-14338)

* exiv2: heap-based buffer overflow in Exiv2::d2Data in types.cpp (CVE-2018-17229)

* exiv2: heap-based buffer overflow in Exiv2::ul2Data in types.cpp (CVE-2018-17230)

* exiv2: NULL pointer dereference in Exiv2::DataValue::copy in value.cpp leading to application crash (CVE-2018-17282)

* exiv2: Stack overflow in CiffDirectory::readDirectory() at crwimage_int.cpp leading to denial of service (CVE-2018-17581)

* exiv2…
