Malicious files can cause the program to enter a large loop #1472
Comments
CVE-2023-39327 was assigned to this flaw. If you wish to dispute or reject please let me know. |
could anyone confirm that this issue was fixed by pull#1547? |
@fundawang the POC is mentioned above. Just run it and report back. |
The pull request confirms that it's not fixed in its description. A slight modification of the PoC allows to trigger the behavior. |
Does anyone has a work around or a fix ready for this issues? |
Is there a fix for this issue yet or will there be one forthcoming anytime soon? Opening a CVE for an issue and letting it hang out for months/years is not really helpful for applications/companies that are using OpenJPEG and are required to react to those CVEs in a specific timeframe. |
How many $$$$$$ do they offer to fix it ? As far as I'm concerned, I don't care at all about companies using OpenJPEG. That's their problem, not mine. |
@mayeut can you provide the file with that slight modification? also how did you know what to alter in the file? |
Maliciously constructed pictures can cause the program to enter a large loop and continuously print warning messages on the terminal.
Expected behavior and actual behavior.
Program file format error, parsing failed~
But the program enters a big loop and keeps printing in the terminal:
I tested it with ubuntu, and the program ran for more than 4 hours.
Steps to reproduce the problem.
the poc is here
Run:
opj_decompress -i bigloop -o te.raw
Maybe the memory must be at least greater than 8g to ensure successful reproduction.
Operating system
Ubuntu, macos, windows are all available
openjpeg version
OpenJPEG 2.5.0
