Tom Lane discovered that ‘ALTER … DEPENDS ON EXTENSION’ sub commands in the PostgreSQL database did not perform authorisation checks.
For Debian 8 ‘Jessie’, this problem has been fixed in version 9.4.26-0+deb8u1.
We recommend that you upgrade your postgresql-9.4_9.4.26-0+deb8u1 packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
