Software Description: - rsync: fast, versatile, remote (and local) file-copying tool 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) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.10: rsync 3.1.2-2ubuntu0.1 Ubuntu 17.04: rsync 3.1.2-1ubuntu0.1 Ubuntu 16.04 LTS: rsync 3.1.1-3ubuntu1.1 Ubuntu 14.04 LTS: rsync 3.1.0-2ubuntu0.3 In general, a standard system update will make all the necessary changes.
