Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An out-of-bounds read was found in Exiv2 versions v0.27.4 and earlier. The out-of-bounds read is triggered when Exiv2 is used to read the metadata of a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service, if they can trick the victim into running Exiv2 on a crafted image file. The bug is fixed in version v0.27.5.

An issue has been found in libde265 v1.0.8 due to incorrect access control. A SEGV caused by a READ memory access in function derive_boundaryStrength of deblock.cc has occurred. The vulnerability causes a segmentation fault and application crash, which leads to remote denial of service.

There's a flaw in OpenEXR's rleUncompress functionality in versions prior to 3.0.5. An attacker who is able to submit a crafted file to an application linked with OpenEXR could cause an out-of-bounds read. The greatest risk from this flaw is to application availability.

An Incorrect Access Control vulnerability exists in libde265 v1.0.8 due to a SEGV in slice.cc.

There's a flaw in OpenEXR's deep tile sample size calculations in versions before 3.0.0-beta.

Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. An out-of-bounds read was found in Exiv2 versions v0.27.3 and earlier. The out-of-bounds read is triggered when Exiv2 is used to write metadata into a crafted image file. An attacker could potentially exploit the vulnerability to cause a denial of service by crashing Exiv2, if they can trick the victim into running Exiv2 on a crafted image file. Note that this bug is only triggered when writing the metadata, which is a less frequently used Exiv2 operation than reading the metadata. For example, to trigger the bug in the Exiv2 command-line application, you need to add an extra command-line argument such as insert. The bug is fixed in version v0.27.4.

The PALM image coder at coders/palm.c makes an improper call to AcquireQuantumMemory() in routine WritePALMImage() because it needs to be offset by 256. This can cause a out-of-bounds read later on in the routine. The patch adds 256 to bytes_per_row in the call to AcquireQuantumMemory(). This could cause impact to reliability. This flaw affects ImageMagick versions prior to 7.0.8-68.

An issue was discovered in Exempi through 2.4.4. A certain case of a 0xffffffff length is mishandled in XMPFiles/source/FormatSupport/PSIR_FileWriter.cpp, leading to a heap-based buffer over-read in the PSD_MetaHandler::CacheFileData() function.

The xmlDictAddString function in libxml2 before 2.9.4, as used in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1, allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.
