Overview
CVE-2022-40755 is a vulnerability discovered in JasPer version 3.0.6, identified on September 16, 2022. The vulnerability affects the image processing functionality within the software, specifically in the inttobits function located in libjasper/base/jas_image.c (MITRE CVE, Debian Tracker).
Technical details
The vulnerability manifests as a reachable assertion in the inttobits function within libjasper/base/jas_image.c. The specific assertion that can be triggered is 'v >= 0 || sgnd', which occurs when parsing crafted JP2 files. This issue was discovered during fuzz testing of the imginfo utility (GitHub Issue).
Impact
When exploited, this vulnerability results in a denial of service condition through the triggering of an assertion failure. This can cause the application using JasPer to terminate unexpectedly when processing specially crafted image files (MITRE CVE).
Exploitability
The vulnerability can be triggered by processing a specially crafted JP2 file using the imginfo utility. A proof of concept has been demonstrated using the command './imginfo -f $POC' which results in the application crash (GitHub Issue).
