Exiv2 has quadratic performance in ICC profile parsing in JpegBase::readMetadata
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
A denial-of-service was found in Exiv2 version v0.28.5: a quadratic algorithm in the ICC profile parsing code in `jpegBase::readMetadata()` can cause Exiv2 to run for a long time. Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted jpg image file.

Matching a version is only one part of assessing exposure. QFinch has not assessed your environment on this public page.
Remediation
Apply the vendor-supported fixed release or mitigation, then verify the affected component is no longer reachable.
- Confirm the affected product and reachable code path exist in your environment.
- Apply the vendor-supported patch or mitigation from the primary advisory.
- Rescan the exact deployed revision and retain verification evidence.
