CVE-2017-17433 [LOW] rsync vulnerabilities
Title: rsync vulnerabilities
Summary: Several security issues were fixed in rsync.
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)
Instructions: In general, a standard system update will make all the necessary changes.
