20 August 2019

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

  o Ubuntu 19.04
  o Ubuntu 18.04 LTS
  o Ubuntu 16.04 LTS

Summary

Several security issues were fixed in CUPS.

Software Description

  o cups - Common UNIX Printing System

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.
