Exiv2 has a denial of service due to unbounded recursion in QuickTimeVideo::multipleEntriesDecoder
Date: 2024-10
Affected: pip/exiv2
Attack vector: dos
Category: vulnerability-disclosure
Severity: Medium
CVE: CVE-2024-24826
CVE-2024-25112
CWE: CWE-125
CWE-400
CWE-674
CVSS: 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H)

### 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. ### For more information Please see our [security policy](https://github.com/Exiv2/exiv2/security/policy) for information about Exiv2 security. ### Credit This bug was found by [OSS-Fuzz](https://github.com/google/oss-fuzz).
