Subject: Re: CVE Request for KNewStuff/KArchive issue

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA256

> When using KNewStuff, one of the KDE Frameworks, to download and install files
> from the internet (e.g. a wallpaper, a plasma applet, etc.), it was possible
> to download a maliciously crafted archive file (e.g. tar.gz or zip) containing
> relative paths leading to outside the extraction directory (say
> "../../../.bashrc" for instance).
> 
> The fix has already been reviewed and submitted:
>    https://git.reviewboard.kde.org/r/128185/
> This fix is one layer below KNewStuff, in the framework called KArchive, which
> handles extraction of .tar.gz / .zip archives. KArchive now prevents files from
> being written outside of the extraction directory, in all cases.

>> Switch to Tar's default behavior to avoid extraction
>> to arbitrary system locations outside of extraction folder. Instead,
>> extract such files to root location in extraction folder.
>> 
>> Submitted with commit 0cb243f64eef45565741b27364cece7d5c349c37 ... to branch master
