USN-6719-1 fixed a vulnerability in util-linux. Unfortunately, it was discovered that the fix did not fully address the issue. This update removes the setgid permission bit from the wall and write utilities.
Original advisory details:
Skyler Ferrante discovered that the util-linux wall command did not filter escape sequences from command line arguments. A local attacker could possibly use this issue to obtain sensitive information.
