Title: FreeRDP vulnerabilities
Summary: Several security issues were fixed in FreeRDP.
It was discovered that FreeRDP incorrectly handled certain memory
operations. A remote attacker could use this issue to cause FreeRDP to
crash, resulting in a denial of service, or possibly execute arbitrary
code.
Instructions: This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
