+Subject: [PATCH] Fix size_t overflow in sa_common.c (GHSL-2022-074)
+
+allocate_structures function located in sa_common.c insufficiently
+checks bounds before arithmetic multiplication allowing for an
+overflow in the size allocated for the buffer representing system
+activities.
+
+This patch checks that the post-multiplied value is not greater than
+UINT_MAX.
