SynopsisThe remote Ubuntu host is missing one or more security-related patches.
DescriptionUSN-148-1 and USN-151-1 fixed two security flaws in zlib, which could be exploited to cause Denial of Service attacks or even arbitrary code execution with malicious data streams.
Most applications use the shared library provided by the 'zlib1g' package; however, some packages contain copies of the affected zlib code, so they need to be upgraded as well.
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 packages.
