Name of the Vulnerable Software and Affected Versions OpenPrinting CUPS versions prior to 2.4.16 Description The CUPS daemon cupsd contains an authorization bypass caused by case-insensitive username comparison during authorization checks. This allows an unprivileged user to gain unauthorized...

Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation in the processing of X.509 certificate paths with DNS name constraints when the end-entity certificate lacks a subject alternative name. An attacker can circumvent DNS name constraints by using a mixed-ca...
