USN-5464-1: e2fsprogs vulnerability

7 June 2022

e2fsprogs could be made to crash or possibly run programs if it processed a specially crafted file system image.

Releases

Packages

  • e2fsprogs - ext2/ext3/ext4 file system utilities

Details

Nils Bars discovered that e2fsprogs incorrectly handled certain file
systems. A local attacker could use this issue with a crafted file
system image to possibly execute arbitrary code.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 22.04
Ubuntu 21.10
Ubuntu 20.04
Ubuntu 18.04
Ubuntu 16.04
Ubuntu 14.04

In general, a standard system update will make all the necessary changes.
