An issue was discovered in Exempi before 2.4.4. Integer overflow in the Chunk class in XMPFiles/source/FormatSupport/RIFF.cpp allows remote attackers to cause a denial of service (infinite loop) via crafted XMP data in a .avi file.(CVE-2017-18233)

An issue was discovered in Exempi before 2.4.3. It allows remote attackers to cause a denial of service (invalid memcpy with resultant use-after-free) or possibly have unspecified other impact via a .pdf file containing JPEG data, related to XMPFiles/source/FormatSupport/ReconcileTIFF.cpp, XMPFiles/source/FormatSupport/TIFF_MemoryReader.cpp, and XMPFiles/source/FormatSupport/TIFF_Support.hpp.(CVE-2017-18234)

An issue was discovered in Exempi before 2.4.4. The ASF_Support::ReadHeaderObject function in XMPFiles/source/FormatSupport/ASF_Support.cpp allows remote attackers to cause a denial of service (infinite loop) via a crafted .asf file.(CVE-2017-18236)

An infinite loop has been discovered in Exempi in the way it handles Extensible Metadata Platform (XMP) data in QuickTime files. An attacker could cause a denial of service via a crafted file.(CVE-2017-18238)

An integer wraparound, leading to a buffer overflow, was found in Exempi in the way it handles Adobe Photoshop Images. An attacker could exploit this to cause a denial of service via a crafted image file.(CVE-2018-7730)

Various issues were discovered in exempi, a library to parse XMP metadata that may cause a denial of service or may have other unspecified impact via crafted files.

CVE-2017-18233 An Integer overflow in the Chunk class in RIFF.cpp allows remote attackers to cause a denial of service (infinite loop) via crafted XMP data in an .avi file.

CVE-2017-18234 An issue was discovered that allows remote attackers to cause a denial of service (invalid memcpy with resultant use-after-free) or possibly have unspecified other impact via a .pdf file containing JPEG data.

CVE-2017-18236 The ASF_Support::ReadHeaderObject function in ASF_Support.cpp allows remote attackers to cause a denial of service (infinite loop) via a crafted .asf file.

CVE-2017-18238 The TradQT_Manager::ParseCachedBoxes function in QuickTime_Support.cpp allows remote attackers to cause a denial of service (infinite loop) via crafted XMP data in a .qt file.

CVE-2018-7728 TIFF_Handler.cpp mishandles a case of a zero length, leading to a heap-based buffer over-read in the MD5Update() function in MD5.cpp.

CVE-2018-7730 A certain case of a 0xffffffff length is mishandled in PSIR_FileWriter.cpp, leading to a heap-based buffer over-read in the PSD_MetaHandler::CacheFileData() function.

For Debian 7 'Wheezy', these problems have been fixed in version 2.2.0-1+deb7u1.

We recommend that you upgrade your exempi packages.
