tinyexr 0.9.5 has an assertion failure in DecodePixelData in tinyexr.h.

Weakness

The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.

Affected Software

Name Vendor Start Version End Version
Tinyexr Tinyexr_project 0.9.5 (including) 0.9.5 (including)
Tinyexr Ubuntu hirsute *
Tinyexr Ubuntu impish *
Tinyexr Ubuntu kinetic *
Tinyexr Ubuntu lunar *
Tinyexr Ubuntu mantic *
Tinyexr Ubuntu trusty *
Tinyexr Ubuntu xenial *

Extended Description

While assertion is good for catching logic errors and reducing the chances of reaching more serious vulnerability conditions, it can still lead to a denial of service. For example, if a server handles multiple simultaneous connections, and an assert() occurs in one single connection that causes all other connections to be dropped, this is a reachable assertion that leads to a denial of service.
