Summary
Several security issues were fixed in CUPS.
Software Description
- 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.
