Releases
Packages
- rsync - fast, versatile, remote (and local) file-copying tool
Details
Danilo Ramos discovered that rsync incorrectly handled memory when
performing certain zlib deflating operations. An attacker could use this
issue to cause rsync to crash, resulting in a denial of service, or
possibly execute arbitrary code.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.04
Ubuntu 18.04
In general, a standard system update will make all the necessary changes.
