Crucial security update for CUPS software on Mageia mitigating risks of denial of service and potential leaks of confidential data.
Updated cups packages fix security vulnerabilities: It was discovered that CUPS incorrectly handled certain language values

Summary

Updated cups packages fix security vulnerabilities:
It was discovered that CUPS incorrectly handled certain language values. A local attacker could possibly use this issue to cause CUPS to crash, leading to a denial of service, or possibly obtain sensitive information (CVE-2019-2228).
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-2019-8675, CVE-2019-8696).
The ippReadIO function may under-read an extension (CVE-2019-8842).
Stephan Zeisberg discovered that CUPS incorrectly handled certain malformed ppd files. A local attacker could possibly use this issue to execute arbitrary code (CVE-2020-3898).
The cups package has been updated to version 2.2.13 and patched to fix these issues and other bugs.
Also, this update will hopefully fix the cups service failing to start at boot on some systems.
