+Subject: [PATCH] libsepol/cil: Check for improper category range
+
+Nicolas Iooss found while fuzzing secilc with AFL that the following
+policy will cause a segfault.
+
+(category c0)
+(category c1)
+(categoryorder (c0 c1))
+(sensitivity s0)
+(sensitivitycategory s0 (range c1 c0))
+
+The category range "(range c1 c0)" is invalid because c1 comes after c0
+in order.
+
+The invalid range is evaluated as containing no categories. There is a
+check for the resulting empty list and the category datum expression is
+set to NULL. The segfault occurs because the datum expression is assumed
+to be non-NULL after evaluation.
+
+Add a check for an invalid range when evaluating category ranges.

+Subject: [PATCH] libsepol/cil: Use an empty list to represent an unknown
+ permission
+
+Nicolas Iooss found while fuzzing secilc with AFL that the statement
+"(classpermissionset CPERM (CLASS (and unknow PERM)))" will cause a
+segfault.
+
+In order to support a policy module package using a permission that
+does not exist on the system it is loaded on, CIL will only give a
+warning when it fails to resolve an unknown permission. CIL itself will
+just ignore the unknown permission. This means that an expression like
+"(and UNKNOWN p1)" will look like "(and p1)" to CIL, but, since syntax
+checking has already been done, CIL won't know that the expression is not
+well-formed. When the expression is evaluated a segfault will occur
+because all expressions are assumed to be well-formed at evaluation time.
+
+Use an empty list to represent an unknown permission so that expressions
+will continue to be well-formed and expression evaluation will work but
+the unknown permission will still be ignored.

+Subject: [PATCH] libsepol/cil: Check that permission is not an empty list
+
+Nicolas Iooss found while fuzzing secilc with AFL that the statement
+"(class C (()))" will cause a segfault.
+
+CIL expects a list of permissions in the class declaration and "(())"
+is a valid list. Each item of the list is expected to be an identifier
+and as the list is processed each item is checked to see if it is a
+list. An error is given if it is a list, otherwise the item is assumed
+to be an identifier. Unfortunately, the check only works if the list
+is not empty. In this case, the item passes the check and is assumed
+to be an identifier and a NULL is passed as the string for name
+verification. If name verification assumes that a non-NULL value will
+be passed in, a segfault will occur.
+
+Add a check for an empty list when processing a permission list and
+improve the error handling for permissions when building the AST.

+Subject: [PATCH] libsepol/cil: Verify neither child nor parent in a bounds is
+ an attribute
+
+Nicolas Iooss found while fuzzing secilc with AFL that using an attribute
+as a child in a typebounds statement will cause a segfault.
+
+This happens because the child datum is assumed to be part of a cil_type
+struct when it is really part of a cil_typeattribute struct. The check to
+verify that it is a type and not an attribute comes after it is used.
+
+This bug effects user and role bounds as well because they do not check
+whether a datum refers to an attribute or not.
+
+Add checks to verify that neither the child nor the parent datum refer
+to an attribute before using them in user, role, and type bounds.

+Subject: [PATCH] libsepol: cil: cil_strpool: Allow multiple strpool users.
+
+cil_strpool currently provides an interface to a statically stored
+global data structure.  This interface does not accomodate multiple
+consumers, however, as two calls to cil_strpool_init() will lead to a
+memory leak and a call to cil_strpool_destroy() by one consumer will
+remove data from use by others, and subsequently lead to a segfault on
+the next cil_strpool_destroy() invocation.
+
+Add a reference counter so that the strpool is only initialized once and
+protect the exported interface with a mutex.
+
+Tested by calling cil_db_init() on two cil_dbs and then calling
+cil_db_destroy() on each.

+The blank default symver fails to compile with ld.gold. This updates the

+for the symbol with the explicit version specified. If there is none, it
+will pick the first listed symbol so there is no breakage.
+This also matches how symvers are defined in libsemanage.

+Subject: [PATCH] libsepol/cil: Exit with an error for an unknown map
+ permission
+
+Nicholas Iooss discovered that using an unknown permission with a
+map class will cause a segfault.
+
+CIL will only give a warning when it fails to resolve an unknown
+permission to support the use of policy module packages that use
+permissions that don't exit on the current system. When resolving
+the unknown map class permission an empty list is used to represent
+the unknown permission. When it is evaluated later the list is
+assumed to be a permission and a segfault occurs.
+
+There is no reason to allow unknown class map permissions because
+the class maps and permissions are defined by the policy.
+
+Exit with an error when failing to resolve a class map permission.

+Subject: [PATCH] libsepol: test for ebitmap_read() negative return value
+
+While fuzzing hll/pp, the fuzzer (AFL) crafted a policy which triggered
+the following message without making the policy loading fail (the
+program crashed with a segmentation fault later):
+
+    security: ebitmap: map size 192 does not match my size 64 (high bit
+    was 0)
+
+This is because ebitmap_read() returned -EINVAL and this value was
+handled as a successful return value by scope_index_read() because it
+was not -1.
+
