Synopsis
The remote Ubuntu host is missing one or more security-related patches.
Description
USN-986-1 fixed vulnerabilities in bzip2. dpkg statically links against libbz2 and needed to be rebuilt to use the updated libbz2.
An integer overflow was discovered in bzip2. If a user or automated system were tricked into decompressing a crafted bz2 file, an attacker could cause bzip2 or any application linked against libbz2 to crash or possibly execute code as the user running the program.
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.
Solution
Update the affected dpkg, dpkg-dev and / or dselect packages.
