FEDORA-2020-01ed02451f
2020-02-02 01:53:29.629340
--------------------------------------------------------------------------------Name        : e2fsprogs
Product     : Fedora 30
Version     : 1.44.6
Release     : 2.fc30
URL         : https://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:

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)  A maliciously corrupted file systems can
trigger buffer overruns in the quota code used by e2fsck.  (Addresses
CVE-2019-5094)  Fix potential use after free in calculate_tree()
