Ubuntu Security Notice USN-4105-1
August 20, 2019

cups vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 19.04
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in CUPS.

Software Description:
- cups: Common UNIX Printing System(tm)

Details:

Stephan Zeisberg discovered that the CUPS SNMP backend incorrectly handled
encoded ASN.1 inputs. A remote attacker could possibly use this issue to
cause CUPS to crash by providing specially crafted network
traffic. (CVE-2019-8696, CVE-2019-8675)

It was discovered that CUPS did not properly handle client disconnection
events. A local attacker could possibly use this issue to cause a denial of
service or disclose memory from the CUPS server.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 19.04:
  cups                            2.2.10-4ubuntu2.1

Ubuntu 18.04 LTS:
  cups                            2.2.7-1ubuntu2.7

Ubuntu 16.04 LTS:
  cups                            2.1.3-4ubuntu0.10

In general, a standard system update will make all the necessary changes.
