Package : sddm
CVE ID : CVE-2020-28049
Debian Bug : 973748
Fabian Vogt discovered a flaw in sddm, a modern display manager for X11.
A local attacker can take advantage of a race condition when creating
the Xauthority file to escalate privileges.
For the stable distribution (buster), this problem has been fixed in
version 0.18.0-1+deb10u1.
We recommend that you upgrade your sddm packages.
For the detailed security status of sddm please refer to its security
tracker page at:
