SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionIt was discovered that the GNU C library did not properly handle memory when processing environment variables for setuid programs. A local attacker could use this in combination with another vulnerability to gain administrative privileges.
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 libc6 package.
