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 8 ‘Jessie’, this problem has been fixed in version 1.42.12-2+deb8u2.
We recommend that you upgrade your e2fsprogs packages.
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.
