"According to the version of the e2fsprogs packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerability :
- 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.Security Fix(es):An exploitable code execution
vulnerability exists in the quota file functionality of
E2fsprogs 1.45.3. A specially crafted ext4 partition
can cause an out-of-bounds write on the heap, resulting
in code execution. An attacker can corrupt a partition
to trigger this vulnerability.(CVE-2019-5094)

description block directly from the EulerOS security advisory. Tenable
