SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionMatthias Gerstner discovered that Timeshift did not securely create temporary files. An attacker could exploit a race condition in Timeshift and potentially execute arbitrary commands as root.
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected timeshift package.
