========================================================================== Ubuntu Security Notice USN-5378-4 April 13, 2022
gzip vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.04 ESM - Ubuntu 14.04 ESM
Summary:
Gzip could be made to overwrite arbitrary files.
Software Description: - gzip: GNU compression utilities
Details:
USN-5378-1 fixed a vulnerability in Gzip. This update provides the corresponding update for Ubuntu 14.04 ESM and 16.04 ESM.
Original advisory details:
Cleemy Desu Wayo discovered that Gzip incorrectly handled certain filenames. If a user or automated system were tricked into performing zgrep operations with specially crafted filenames, a remote attacker could overwrite arbitrary files.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 ESM: gzip 1.6-4ubuntu1+esm1
Ubuntu 14.04 ESM: gzip 1.6-3ubuntu1+esm1
In general, a standard system update will make all the necessary changes.
