"This update for exiv2 fixes the following issues :

CVE-2017-11591: A floating point exception in the Exiv2::ValueType
function could lead to a remote denial of service attack via crafted
input. (bsc#1050257)

CVE-2017-14864: An invalid memory address dereference was discovered
in Exiv2::getULong in types.cpp. The vulnerability caused a
segmentation fault and application crash, which lead to denial of
service. (bsc#1060995)

CVE-2017-14862: An invalid memory address dereference was discovered
in Exiv2::DataValue::read in value.cpp. The vulnerability caused a
segmentation fault and application crash, which lead to denial of
service. (bsc#1060996)

CVE-2017-14859: An invalid memory address dereference was discovered
in Exiv2::StringValueBase::read in value.cpp. The vulnerability caused
a segmentation fault and application crash, which lead to denial of
service. (bsc#1061000)

CVE-2017-11683: There is a reachable assertion in the
Internal::TiffReader::visitDirectory function in tiffvisitor.cpp that
could lead to a remote denial of service attack via crafted input.
(bsc#1051188)

CVE-2017-17669: There is a heap-based buffer over-read in the
Exiv2::Internal::PngChunk::keyTXTChunk function of pngchunk_int.cpp. A
crafted PNG file would lead to a remote denial of service attack.
(bsc#1072928)

CVE-2018-10958: In types.cpp a large size value might have lead to a
SIGABRT during an attempt at memory allocation for an
Exiv2::Internal::PngChunk::zlibUncompress call. (bsc#1092952)

CVE-2018-10998: readMetadata in jp2image.cpp allowed remote attackers
to cause a denial of service (SIGABRT) by triggering an incorrect
Safe::add call. (bsc#1093095)

CVE-2018-11531: Exiv2 had a heap-based buffer overflow in getData in
preview.cpp. (bsc#1095070)
