Exiv2 has a denial of service due to unbounded recursion in QuickTimeVideo::multipleEntriesDecoder
Impact
A denial-of-service was found in Exiv2 version v0.28.1: an unbounded recursion can cause Exiv2 to crash by exhausting the stack. The vulnerable function, QuickTimeVideo::multipleEntriesDecoder, was new in v0.28.0 (see https://github.com/Exiv2/exiv2/pull/2337), so Exiv2 versions before v0.28 are not affected. 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 video file.
Patches
The bug is fixed in version v0.28.2.
