-Subject: [PATCH] libsepol/cil: Verify alias in aliasactual statement is really
- an alias
-
-Nicolas Iooss found while fuzzing secilc with AFL that the statement
-"(sensitivityaliasactual SENS SENS)" will cause a segfault.
-
-The segfault occurs because when the aliasactual is resolved the first
-identifier is assumed to refer to an alias structure, but it is not.
-
-Add a check to verify that the datum retrieved is actually an alias
-and exit with an error if it is not.
-
