-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-2627-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb April 15, 2021 https://wiki.debian.org/LTS - -------------------------------------------------------------------------
Package : xorg-server Version : 2:1.19.2-1+deb9u8 CVE ID : CVE-2021-3472 Jan-Niklas Sohn discovered that there was an input validation failure in the X.Org display server. Insufficient checks on the lengths of the XInput extension's ChangeFeedbackControl request could have lead to out of bounds memory accesses in the X server. These issues can lead to privilege escalation for authorised clients, particularly on systems where the X server is running as a privileged user. For Debian 9 "Stretch", this problem has been fixed in version 2:1.19.2-1+deb9u8. We recommend that you upgrade your xorg-server packages. For the detailed security status of xorg-server please refer to its security tracker page at: https://security-tracker.debian.org/tracker/xorg-server Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEwv5L0nHBObhsUz5GHpU+J9QxHlgFAmB4E6AACgkQHpU+J9Qx Hlj6qw//ZBpTkP0Af19OglE2NR3AujsTErxp4lI8sc5LwOlXtnfcVFEpl4kpLBpR suMrlmkryaedBBl0Zeq8qnoimuMPdhiTing+77I1YW7hNfhwZJdDjLsoVFG5qXe6 D9/fD683vgL4IiKdHxLNfqcaaL8QYm2KmyKLbHsTvQ+12b7pq9TwenbIHGloGV7K nsTZrXkx37loi5cdYHQLw09qKYXcTaQx+GZ7XH0UgiJi4XJCjY7gr6/4+qnqVYW/ OnpmGYh9SycH1cFHkPfmWDGrBd3omKStkx7keBXXBQVgyyUpIDp9A3J62lM3vX9U czexLKJTCx77CviBFcJYigi41ST/XT/HCVy2pkvxv7d6KXA+fCKPL7jogBy43Zfy 3d2SL9mH7MxAfP5TVOsmShPrLqY9FGm0MteXjSKX7inoAxJmJx9F2w7JtzfNNDpG 2a0mJABw4ZRRiEL5OlEonAwqExyR+LO6cFA+xWKmZwsy4lMEeOBo3RAzX+U21iLB wDATwPL0Q97XM3b3iOJShCXr2nWYrNhd2mWFFEewXVEZWvSVqyI9uVtr9FW6/0YJ LD9jXp1BBbt7/bMZv+KSLVMavKLOu4Vm6bwClKX5NYS1ZRXWVX71XkuId5ntpoco raxAtjWgda1KidFGStU2ABoFoil4tyWhg7CuB+KCoyfVhIiM4Wg= =eyBB -----END PGP SIGNATURE-----
