Package : postgresql-9.6
Version : 9.6.23-0+deb9u1
CVE ID : CVE-2021-3449
PostgreSQL 9.6.23 fixes this security issue:
Disallow SSL renegotiation more completely (Michael Paquier)
SSL renegotiation has been disabled for some time, but the server would
still cooperate with a client-initiated renegotiation request. A
maliciously crafted renegotiation request could result in a server crash
(see OpenSSL issue CVE-2021-3449). Disable the feature altogether on
OpenSSL versions that permit doing so, which are 1.1.0h and newer.
For Debian 9 stretch, this problem has been fixed in version
9.6.23-0+deb9u1.
We recommend that you upgrade your postgresql-9.6 packages.
For the detailed security status of postgresql-9.6 please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/postgresql-9.6
Further information about Debian LTS security advisories, how to apply
these updates to your system and frequently asked questions can be
