CVE-2024-25112

Name	CVE-2024-25112
Description	Exiv2 is a command-line utility and C++ library for reading, writing, deleting, and modifying the metadata of image files. 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, so Exiv2 versions before v0.28 are _not_ affected. The denial-of-service is triggered when Exiv2 is used to read the metadata of a crafted video file. This bug is fixed in version v0.28.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.

GHSA mentions new in v0.28.0, but that only applies to the "main" branch, where
it was removed and later reintroduced. The 0.27-maintenance branch _does_ include
the Quicktime decoder
