(RHSA-2020:1577) Moderate: exiv2 security, bug fix, and enhancement update

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: infinite loop in Exiv2::Image::printIFDStructure function in image.cpp (CVE-2018-18915)

• exiv2: heap-based buffer over-read in Exiv2::IptcParser::decode in iptc.cpp (CVE-2018-19107)

• exiv2: infinite loop in Exiv2::PsdImage::readMetadata in psdimage.cpp (CVE-2018-19108)

• exiv2: heap-based buffer over-read in PngChunk::readRawProfile in pngchunk_int.cpp (CVE-2018-19535)

• exiv2: NULL pointer dereference in Exiv2::isoSpeed in easyaccess.cpp (CVE-2018-19607)

• exiv2: Heap-based buffer over-read in Exiv2::tEXtToDataBuf function resulting in a denial of service (CVE-2018-20096)

• exiv2: Segmentation fault in Exiv2::Internal::TiffParserWorker::findPrimaryGroups function (CVE-2018-20097)

• exiv2: Heap-based buffer over-read in Exiv2::Jp2Image::encodeJp2Header resulting in a denial of service (CVE-2018-20098)

• exiv2: Infinite loop in Exiv2::Jp2Image::encodeJp2Header resulting in a denial of service (CVE-2018-20099)

• exiv2: infinite recursion in Exiv2::Image::printTiffStructure in file image.cpp resulting in denial of service (CVE-2019-9143)

• exiv2: denial of service in PngImage::readMetadata (CVE-2019-13109)

• exiv2: integer overflow in WebPImage::decodeChunks leads to denial of service (CVE-2019-13111)

• exiv2: uncontrolled memory allocation in PngChunk::parseChunkContent causing denial of service (CVE-2019-13112)

• exiv2: invalid data location in CRW image file causing denial of service (CVE-2019-13113)

• exiv2: null-pointer dereference in http.c causing denial of service (CVE-2019-13114)
