[EnchantedJohn]

The third Error is also Segmentation fault .I also use AFL tools
The error is :

[fgeek]

CVE-2018-10972 has been assigned for this issue (not requested by me).

[fgeek]

@EnchantedJohn include sample PoC file to this issue e.g. inside zip file.

[paride]

@jonsneyers FLIF is marked for autoremoval from Debian testing on Sat 09 Jun 2018 as this is considered a grave security issue...

[EnchantedJohn]

Thanks,guys,I will close this issue.

[fgeek]

Err what @EnchantedJohn. Why did you close this? This is not fixed.

[lgbaldoni]

What? The problem is still there on openSUSE Tumbleweed. If you don't plan on fixing this and the other security issues, please tell for I need to know how to proceed.

[fgeek]

@luigino I don't think that upstream has commented on this case. This should be reopened and fixed. I personally don't have skills to create a PR.

[lgbaldoni]

@fgeek right, sorry.
@EnchantedJohn why did you close this?

[paride]

@jonsneyers If these issues (#503, #501, #509, #505, #504, #502 and others from @EnchantedJohn, plus #498) can't be addressed in the short term, I'll have to pull FLIF from Debian for the moment. The bugs are grave, and without fixing them the package won't make it to Debian testing (or stable) anyway. This doesn't mean the package can't be made part of Debian again in the future, after bringing it in better shape. I prefer to pull it before any other package sets a dependency on it.

[lgbaldoni]

@paride I don't think the developer cares.
Anyway the package was pulled from openSUSE as well.
