========================================================================== Ubuntu Security Notice USN-3348-1 July 05, 2017 samba vulnerability ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.04 - Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: Samba could be made to hang if it received specially crafted network traffic. Software Description: - samba: SMB/CIFS file, print, and login server for Unix Details: It was discovered that Samba incorrectly handled dangling symlinks. A remote attacker could possibly use this issue to cause Samba to hang, resulting in a denial of service. This issue only applied to Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2017-9461) In addition, this update fixes a regression introduced by USN-3267-1 that caused Samba to incorrectly handle non-wide symlinks to directories. Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.04: samba 2:4.5.8+dfsg-0ubuntu0.17.04.3 Ubuntu 16.10: samba 2:4.4.5+dfsg-2ubuntu5.7 Ubuntu 16.04 LTS: samba 2:4.3.11+dfsg-0ubuntu0.16.04.8 Ubuntu 14.04 LTS: samba 2:4.3.11+dfsg-0ubuntu0.14.04.9 In general, a standard system update will make all the necessary changes.
