+ Changes
+
+
+
+
+
+
+ Improve behavior of libpq's quoting
+ functions (Andres Freund, Tom Lane)
+ §
+ §
+ §
+
+
+
+ The changes made for CVE-2025-1094 had one serious oversight:
+ PQescapeLiteral()
+ and PQescapeIdentifier() failed to honor their
+ string length parameter, instead always reading to the input
+ string's trailing null. This resulted in including unwanted text in
+ the output, if the caller intended to truncate the string via the
+ length parameter. With very bad luck it could cause a crash due to
+ reading off the end of memory.
+
+
+
+ In addition, modify all these quoting functions so that when invalid
+ encoding is detected, an invalid sequence is substituted for just
+ the first byte of the presumed character, not all of it. This
+ reduces the risk of problems if a calling application performs
+ additional processing on the quoted string.
+
+
+
+
+
+
+ Fix small memory leak
+ in pg_createsubscriber (Ranier Vilela)
+ §
+
+
+
+
+
+
+ Fix meson build system to correctly detect availability of
+ the bsd_auth.h system header
+ (Nazir Bilal Yavuz)
