Crash with RAR5 archive

[RowlaxX]

Hello, I have a java program that download RAR5 files and then extract them with your library. It's working correctly for hundreds of files, exept for this file. This file contains two items, and only the first one is extractable, the second one, when extracting, cause the JVM crashing.

When I use an external program like 7Zip, the extraction works good.

Here is the link of the file : https://d4cjuq.am.files.1drv.com/y4mJMhky-MQnlTmVlLD8Nu8jtpjM24blPAEgBuASPdp_S0soTqM44pdu9ZJMwLHO5ih81bhjI3nqVr1qhMsbuMwfMTi1BrrUtzMUvXy1rwpao9RJeTnyVVeWH5ViXTewhJAbA5iL2Of3M-uQi7MY5jwv4dkf8i3wDB6TTNdzJfEziYlVY-M1isxB3ZCiMT-JMwb/UnRenamed%20Files%20-%20Commodore%208Bits%20(2020-04-25).rar?download&psid=1

Hello RowlaxX,

thank you for reporting the issue. I will look into it and come back to you.

Cheers, Boris Brodski

[RowlaxX]

Thank you ! I will upload the file to another host if you are not able to grab it

[borisbrodski]

Yes please, upload it to some other cloud, so I can download it. Currently I get 404.

I can confirm, that your file crashes p7zip 16.02, so it seems to be the 7-zip problem, not the binding problem.

[jinfeihan57]

@borisbrodski can you try this p7zip 17.02. https://github.com/szcnick/p7zip

[borisbrodski]

p7zip 17.02 can extract the archive 👍

I will upgrade 7-Zip-JBinding to the 17.02 version. But it has also to pass all a couple thousands of my tests though. ;)

I donated you a few bucks. This is not a huge ammount, but that’s a beer ! 😉Thank you for your hard work ! Provenance : Courrier pour Windows 10 De : Boris BrodskiEnvoyé le :mardi 1 septembre 2020 10:30À : borisbrodski/sevenzipjbindingCc : RowlaxX; AuthorObjet :Re: [borisbrodski/sevenzipjbinding] Crash with RAR5 archive (#26) p7zip 17.02 can extract the archive 👍I will upgrade 7-Zip-JBinding to the 17.02 version.But it has also to pass all a couple thousands of my tests though. ;)—You are receiving this because you authored the thread.Reply to this email directly, view it on GitHub, or unsubscribe.

@borisbrodski so when can we expect new version with updated p7zip? :)

[sunny-shu]

@RowlaxX the download url is broken, i cannot download the file. @borisbrodski i am a member of p7zip，i will test this project with new version.

[borisbrodski]

@bartektartanus Thank you for posting it here :)

Can you please check, if you can or can not extract your RAR file with p7zip 16.02? It p7zip 16.02 crashes, could you try to extract your RAR with p7zip 17.02 from here (https://github.com/szcnick/p7zip) or upload your RAR file, so I can check it.

(This crash looks a bit weird to me. Maybe there is some other problem.)

Thank you very much!

[sunny-shu]

@bartektartanus p7zip 17.01 is based on p7zip 16.02 and fix the CVES，It is compatible with 16.02。 you can replace the source code with p7zip 17.01, then build the project 'sevenzipjbinding' and test if it is ok.

p7zip 17.02 update the 7z version to 17.01,files and apis changes a lot; so it will fail when building sevenzipjbinding with p7zip 17.02. anyway, i don't get crash when unpack the rar5 file with p7zip 16.02,can you upload the file?

[borisbrodski]

@sunny-shu good to know. Thank you. I will integrate p7zip and 7zip 17.02 in a while, when I'm done expanding my test infrastructure.
