USN-4105-1: CUPS vulnerabilities

Releases

• Ubuntu 19.04
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• 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.

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

Ubuntu 19.04
