+postgresql-13 (13.19-0+deb11u1) bullseye-security; urgency=medium
+
+  * New upstream version 13.19.
+
+    + Harden PQescapeString and allied functions against invalidly-encoded
+      input strings (Andres Freund, Noah Misch)
+
+      Data-quoting functions supplied by libpq now fully check the encoding
+      validity of their input.  If invalid characters are detected, they
+      report an error if possible.  For the ones that lack an error return
+      convention, the output string is adjusted to ensure that the server will
+      report invalid encoding and no intervening processing will be fooled by
+      bytes that might happen to match single quote, backslash, etc.
+
+      The purpose of this change is to guard against SQL-injection attacks
+      that are possible if one of these functions is used to quote crafted
+      input.  There is no hazard when the resulting string is sent directly to
+      a PostgreSQL server (which would check its encoding anyway), but there
+      is a risk when it is passed through psql or other client-side code.
+      Historically such code has not carefully vetted encoding, and in many
+      cases it's not clear what it should do if it did detect such a problem.
+
+      This fix is effective only if the data-quoting function, the server, and
+      any intermediate processing agree on the character encoding that's being
+      used.  Applications that insert untrusted input into SQL commands should
+      take special care to ensure that that's true.
+
+      Applications and drivers that quote untrusted input without using these
+      libpq functions may be at risk of similar problems.  They should first
+      confirm the data is valid in the encoding expected by the server.
+
+      The PostgreSQL Project thanks Stephen Fewer for reporting this problem.
+      (CVE-2025-1094)
