Ubuntu: USN-6801-1 Severity: e2fsprogs Buffer Overflow Fix

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.
