+ libpq can leak memory contents after
+ GSSAPI transport encryption initiation fails (Jacob Champion)
+
+
+
+ A modified server, or an unauthenticated man-in-the-middle, can
+ send a not-zero-terminated error message during setup of GSSAPI
+ (Kerberos) transport encryption. libpq
+ will then copy that string, as well as following bytes in
+ application memory up to the next zero byte, to its error report.
+ Depending on what the calling application does with the error
+ report, this could result in disclosure of application memory
+ contents. There is also a small probability of a crash due to
+ reading beyond the end of memory. Fix by properly zero-terminating
+ the server message.
+ (CVE-2022-41862)
