Lifecycle Timeline
1DescriptionNVD
In libjpeg-turbo 2.0.2, a large amount of memory can be used during processing of an invalid progressive JPEG image containing incorrect width and height values in the image header. NOTE: the vendor's expectation, for use cases in which this memory usage would be a denial of service, is that the application should interpret libjpeg warnings as fatal errors (aborting decompression) and/or set limits on resource consumption or image sizes
AnalysisAI
In libjpeg-turbo 2.0.2, a large amount of memory can be used during processing of an invalid progressive JPEG image containing incorrect width and height values in the image header. Rated medium severity (CVSS 5.5), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Allocation of Resources Without Limits (CWE-770), which allows attackers to exhaust system resources through uncontrolled allocation. In libjpeg-turbo 2.0.2, a large amount of memory can be used during processing of an invalid progressive JPEG image containing incorrect width and height values in the image header. NOTE: the vendor's expectation, for use cases in which this memory usage would be a denial of service, is that the application should interpret libjpeg warnings as fatal errors (aborting decompression) and/or set limits on resource consumption or image sizes Affected products include: Libjpeg-Turbo.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Set resource limits, implement rate limiting, validate input sizes.
