Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2022-05-02 18:45:19 UTC 
CVE-2022-29973:

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 https://github.com/relan/exfat/tree/validsize
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 
https://github.com/relan/exfat/issues/185 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.
Comment 4 John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2023-03-11 04:50:59 UTC 
Issue says fixed in 1.4.0
