Summary
Exiv2 Segmentation Faults in Exiv2::EpsImage::writeMetadata() via crafted EPS file
Details

Impact

An out-of-bounds read was found in Exiv2 versions v0.28.5 and earlier. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. 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 delete.

Patches

The bug is fixed in version v0.28.6.
