Name : e2fsprogs Product : Fedora 30 Version : 1.44.6 Release : 2.fc30 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:
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() -------------------------------------------------------------------------------- ChangeLog:
