AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions: xpdf version 4.00

Description: The issue allows attackers to launch a denial of service via a specific pdf file, resulting in a heap-based buffer over-read and application crash. This can be achieved by exploiting the JPXStream::inverseTransformLevel function in JPXStream.cc.

Recommendations: For xpdf version 4.00, consider avoiding the use of the JPXStream::inverseTransformLevel function until a patch is available. As a temporary workaround, restrict the processing of pdf files that may trigger the heap-based buffer over-read to minimize the risk of application crash.
