Details

USN-3506-1 fixed two vulnerabilities in rsync. This update provides
the corresponding update for Ubuntu 12.04 ESM.

Original advisory details:

It was discovered that rsync proceeds with certain file metadata updates
before checking for a filename. An attacker could use this to bypass access
restrictions. (CVE-2017-17433)

It was discovered that rsync does not check for fnamecmp filenames and also
does not apply the sanitize_paths protection mechanism to pathnames. An attacker
could use this to bypass access restrictions. (CVE-2017-17434)
