Fedora Update Notification
FEDORA-2020-a724cc7926

——————————————————————————–

Name : e2fsprogs
Product : Fedora 31
Version : 1.45.5
Release : 1.fc31
URL : http://e2fsprogs.sourceforge.net/
Summary : Utilities for managing ext2, ext3, and ext4 file systems
Description :
The e2fsprogs package contains a number of utilities for creating,
checking, modifying, and correcting any inconsistencies in second,
third and fourth extended (ext2/ext3/ext4) file systems. E2fsprogs
contains e2fsck (used to repair file system inconsistencies after an
unclean shutdown), mke2fs (used to initialize a partition to contain
an empty ext2 file system), debugfs (used to examine the internal
structure of a file system, to manually repair a corrupted
file system, or to create test cases for e2fsck), tune2fs (used to
modify file system parameters), and most of the other core ext2fs
file system utilities.

You should install the e2fsprogs package if you need to manage the
performance of an ext2, ext3, or ext4 file system.

Update Information:

Fixes —– A maliciously corrupted file systems can trigger buffer overruns in
the quota code used by e2fsck. (Addresses CVE-2019-5094) E2fsck now checks to
make sure the casefold flag is only set on directories, and only when the
casefold feature is enabled. E2fsck will not disable the low dtime checks when
using a backup superblock where the last mount time is zero. This fixes a
failure in xfstests ext4/007. Fix e2fsck so that when it needs to recreate the
root directory, the quota counts are correctly updated. Fix e2scrub_all cron
script so it checks to make sure e2scrub_all exists, since the crontab and cron
script might stick around after the e2fsprogs package is removed. (Addresses
Debian Bug: #932622) Fix e2scrub_all so that it works when the free space is
exactly the snapshot size. (Addresses Debian Bug: #935009) Avoid spurious lvm
warnings when e2scrub_all is run out of cron on non-systemd systems (Addresses
Debian Bug: #940240) Update the man pages to document the new fsverity feature,
and improve the documentation for the casefold and encrypt features. E2fsck
will no longer force a full file system check if time-based forced checks are
disabled and the last mount time or last write time in the superblock are in the
future. Fix a potential out of bounds write when checking a maliciously
corrupted file system. This is probably not exploitable on 64-bit platforms,
but may be exploitable on 32-bit binaries depending on how the compiler lays out
the stack variables. (Addresses CVE-2019-5188) Fixed spurious weekly e-mails
when e2scrub_all is run via a cron job on non-systemd systems. (Addresses
Debian Bug: #944033) Remove an unnecessary sleep in e2scrub which could add up
to an additional two second delay during the boot up. Also, avoid trying to
reap aborted snapshots if it has been disabled via e2scrub.conf. (Addresses
Debian Bug: #948193) If a mischievous system administrator mounts a pseudo-file
system such as tmpfs with a device name that duplicates another mounted file
system, this could potentially confuse resize2fs when it needs to find the mount
point of a mounted file system. (Who would have guessed?) Add some sanity
checking so that we can make libext2fs more robust against such insanity, at
least on Linux. (GNU HURD doesn’t support st_rdev.) Tune2fs now prohibits
enabling or disabling uninit_bg if the file system is mounted, since this could
result in the file system getting corrupted, and there is an unfortunate
AskUbuntu article suggesting this as a way to modify a file system’s UUID on a
live file system. (Ext4 now has a way to do this safely, using the
metadata_csum_seed feature, which was added in the 4.4 Linux kernel.) Fix
potential crash in e2fsck when rebuilding very large directories on file systems
which have the new large_dir feature enable. Fix support of 32-bit uid’s and
gid’s in fuse2fs and in mke2fs -d. Fix mke2fs’s setting bad blocks to bigalloc
file systems. Fix a bug where fuse2fs would incorrectly report the i_blocks
fields for bigalloc file systems. Resize2fs’s minimum size estimates (via
resize2fs -M) estimates are now more accurate when run on mounted file systems.
Fixed potential memory leak in read_bitmap() in libext2fs. Fixed various UBsan
failures found when fuzzing file system images. (Addresses Google Bug:
#128130353) Updated and clarified various man pages. Performance, Internal
Implementation, Development Support etc.
————————————————————– Fixed various
debian packaging issues. (Addresses Debian Bug: #933247, #932874, #932876,
#932855, #932859, #932861, #932881, #932888) Fix false positive test failure in
f_pre_1970_date_encoding on 32-bit systems with a 64-bit time_t. (Addresses
Debian Bug: #932906) Fixed various compiler warnings. (Addresses Google Bug
#118836063) Update the Czech, Dutch, French, German, Malay, Polish, Portuguese,
Spanish, Swedish, Ukrainian, and Vietnamese translations from the Translation
Project. Speed up e2fsck on file systems with a very large number of inodes
caused by repeated calls to gettext(). The inode_io io_manager can now support
files which are greater than 2GB. The ext2_off_t and ext2_off64_t are now
signed types so that ext2fs_file_lseek() and ext2fs_file_llseek() can work
correctly. Reserve codepoint for the fast_commit feature. Fixed various Debian
packaging issues. Fix portability problems for Illumous and on hurd/i386
(Addresses Debian Bug: #944649) Always compile the ext2fs_swap_* functions even
on little-endian architectures, so that debian/libext2fs.symbols can be
consistent across architectures. Synchronized changes from Android’s AOSP
e2fsprogs tree. Updated config.guess and config.sub with newer versions from
the FSF. Update the Chinese and Malay translations from the translation
project.
