+# Resource leakage when decoding certificates and keys
+
+The `OPENSSL_LH_flush()` function, which empties a hash table, contains
+a bug that breaks reuse of the memory occupied by the removed hash
+table entries.
+
+This function is used when decoding certificates or keys. If a long lived
+process periodically decodes certificates or keys its memory usage will
+expand without bounds and the process might be terminated by the operating
+system causing a denial of service. Also traversing the empty hash table
+entries will take increasingly more time.
+
+Typically such long lived processes might be TLS clients or TLS servers
+configured to accept client certificate authentication.
