========================================================================== Ubuntu Security Notice USN-3506-1 December 07, 2017
rsync vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10 - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in rsync.
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.
