Exiv2 has a denial of service due to unbounded recursion in QuickTimeVideo::multipleEntriesDecoder

Moderate severity GitHub Reviewed Published Feb 12, 2024 in Exiv2/exiv2 • Updated Oct 18, 2024

Package

pip exiv2 (pip)

Affected versions

= 0.16.0

Patched versions

0.16.1

Description

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 Exiv2/exiv2#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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
