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. Update Instructions: Run sudo pro fix USN-6719-2 to fix the vulnerability. The problem can be corrected by updating your system to the following package versions: bsdutils – 1:2.34-0.1ubuntu9.6 No subscription required fdisk – 2.34-0.1ubuntu9.6 libblkid-dev – 2.34-0.1ubuntu9.6 libblkid1 – 2.34-0.1ubuntu9.6 libfdisk-dev – 2.34-0.1ubuntu9.6 libfdisk1 – 2.34-0.1ubuntu9.6 libmount-dev – 2.34-0.1ubuntu9.6 libmount1 – 2.34-0.1ubuntu9.6 libsmartcols-dev – 2.34-0.1ubuntu9.6 libsmartcols1 – 2.34-0.1ubuntu9.6 libuuid1 – 2.34-0.1ubuntu9.6 mount – 2.34-0.1ubuntu9.6 rfkill – 2.34-0.1ubuntu9.6 util-linux – 2.34-0.1ubuntu9.6 util-linux-locales – 2.34-0.1ubuntu9.6 uuid-dev – 2.34-0.1ubuntu9.6 uuid-runtime – 2.34-0.1ubuntu9.6 No subscription required
