rsync vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in rsync.
Software Description
It was discovered that rsync incorrectly handled pointer arithmetic in zlib. An attacker could use this issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-9840, CVE-2016-9841)
It was discovered that rsync incorrectly handled vectors involving left shifts of negative integers in zlib. An attacker could use this issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-9842)
It was discovered that rsync incorrectly handled vectors involving big-endian CRC calculation in zlib. An attacker could use this issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2016-9843)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.04 LTS
rsync - 3.1.2-2.1ubuntu1.1
Ubuntu 16.04 LTS
rsync - 3.1.1-3ubuntu1.3
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
