"An issue has been found in e2fsprogs, a package that contains
ext2/ext3/ext4 file system utilities. A specially crafted ext4
directory can cause an out-of-bounds write on the stack, resulting in
code execution. An attacker can corrupt a partition to trigger this
vulnerability.

For Debian 9 stretch, this problem has been fixed in version
1.43.4-2+deb9u2.

We recommend that you upgrade your e2fsprogs packages.

For the detailed security status of e2fsprogs please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/e2fsprogs

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues.");
