Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-05-02 18:45:19 UTC

relan exFAT 1.3.0 allows local users to obtain sensitive information (data from deleted files in the filesystem) in certain situations involving offsets beyond ValidDataLength.

Possibly incorrect patches in
Comment 1 Mike Gilbert gentoo-dev 2022-05-02 18:52:50 UTC
This affects sys-fs/fuse-exfat, not sys-fs/exfat-utils.
Comment 2 Federico Justus Denkena 2022-09-17 20:11:07 UTC states the need for a bit of "polishing". Should the patch still be pulled? Or should we wait for upstream to get the patch to a desired state?
Comment 3 Mike Gilbert gentoo-dev 2022-09-17 20:59:17 UTC
I plan to wait until upstream merges some change to the master branch.
