Much of the formula is bloated and superfluous.
Avoid the assertion failure in the JPC_QCX_EXPN() function. While the "expn" variable cannot be bigger than 0x1f, adding something to it may exceed that limit. This condition could be exploited with a malicious JP2 file, allowing a denial of service attack on processes which parse JP2 files.

Since this repository is abandoned and @mdadams has not replied for several years to my code submissions and emails, I'll be moving my efforts to fix Jasper to https://github.com/jasper-maint/jasper |
