CVE-2019-13112

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.

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)

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)
