USN-3911-2: file regression

13 May 2020

USN-3911-1 introduced a regression in file.



  • file - Tool to determine file types


USN-3911-1 fixed vulnerabilities in file. One of the backported security
fixes introduced a regression that caused the interpreter string to be
truncated. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that file incorrectly handled certain malformed ELF
files. An attacker could use this issue to cause a denial of service, or
possibly execute arbitrary code.

Update instructions

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

Ubuntu 18.04
Ubuntu 16.04

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