Description

The updated packages fix security vulnerabilities:

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)

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 chunkLength - iccOffset subtraction.
(CVE-2019-13109)

A CiffDirectory::readDirectory integer overflow and out-of-bounds read
in Exiv2 through 0.27.1 allows an attacker to cause a denial of service
(SIGSEGV) via a crafted CRW image file. (CVE-2019-13110)

A PngChunk::parseChunkContent uncontrolled memory allocation in Exiv2
through 0.27.1 allows an attacker to cause a denial of service (crash
due to an std::bad_alloc exception) via a crafted PNG image file.
(CVE-2019-13112)

Exiv2 through 0.27.1 allows an attacker to cause a denial of service
(crash due to assertion failure) via an invalid data location in a
CRW image file. (CVE-2019-13113)

http.c in Exiv2 through 0.27.1 allows a malicious http server to cause a
denial of service (crash due to a NULL pointer dereference) by returning
a crafted response that lacks a space character. (CVE-2019-13114)

Exiv2 0.27.2 allows attackers to trigger a crash in Exiv2::getULong in
types.cpp when called from Exiv2::Internal::CiffDirectory::readDirectory
in crwimage_int.cpp, because there is no validation of the relationship
of the total size to the offset and size. (CVE-2019-17402)
