Unintentional integer overflow in LongNameSetPermissionCollection ----------------------------------------------------------------- Key: ELY-611 URL: https://issues.jboss.org/browse/ELY-611 Project: WildFly Elytron Issue Type: Bug Affects Versions: 1.1.0.Beta7 Reporter: Ondrej Lukas Assignee: Darran Lofthouse Labels: static_analysis Fix For: 1.1.0.Beta8 There are potentially overflowing expressions in org.wildfly.security.permission.LongNameSetPermissionCollection in {{getBitsForName}} method. Expressions {{1 << nameEnumeration.size()}} and {{1 << nameEnumeration.indexOf(name)}} are evaluated as integer but assigned to {{bits}} variable which is long. It can be avoided by casting {{1}} to long.
