If a materialized view's owner could persuade a superuser or other high-privileged user to perform a concurrent refresh on that view, the view's owner could control code executed with the privileges of the user running REFRESH. Fix things so that all user-determined code is run as the view's owner, as expected. The PostgreSQL Project thanks Pedro Gallegos for reporting this problem. (CVE-2024-0985) -- Christoph Berg Tue, 06 Feb 2024 13:37:19 +0100 postgresql-15 (15.5-0+deb12u1~progress6.99u1) fuchur-backports; urgency=medium * Initial reupload to fuchur-backports. * Updating maintainer field. * Updating uploaders field. * Updating bugs field. * Updating vcs fields. -- Daniel Baumann Sat, 04 May 2024 14:17:41 +0200 postgresql-15 (15.5-0+deb12u1) bookworm-security; urgency=medium * New upstream version. * Fix handling of unknown-type arguments in DISTINCT "any" aggregate functions (Tom Lane) This error led to a text-type value being interpreted as an unknown-type value (that is, a zero-terminated string) at runtime. This could result in disclosure of server memory following the text value. The PostgreSQL Project thanks Jingzhou Fu for reporting this problem. (CVE-2023-5868) * Detect integer overflow while computing new array dimensions (Tom Lane) When assigning new elements to array subscripts that are outside the current array bounds, an undetected integer overflow could occur in edge cases. Memory stomps that are potentially exploitable for arbitrary code execution are possible, and so is disclosure of server memory. The PostgreSQL Project thanks Pedro Gallegos for reporting this problem. (CVE-2023-5869) * Prevent the pg_signal_backend role from signalling background workers and autovacuum processes (Noah Misch, Jelte Fennema-Nio) The documentation says that pg_signal_backend cannot issue signals to superuser-owned processes. It was able to signal these background processes, though, because they advertise a role OID of zero. Treat that as indicating superuser ownership. The security implications of cancelling one of these process types are fairly small so far as the core code goes (we'll just start another one), but extensions might add background workers that are more vulnerable. Also ensure that the is_superuser parameter is set correctly in such processes. No specific security consequences are known for that oversight, but it might be significant for some extensions. The PostgreSQL Project thanks Hemanth Sandrana and Mahendrakar Srinivasarao for reporting this problem. (CVE-2023-5870) * Fix misbehavior during recursive page split in GiST index build (Heikki Linnakangas) Fix a case where the location of a page downlink was incorrectly tracked, and introduce some logic to allow recovering from such situations rather than silently doing the wrong thing. This error could result in incorrect answers from subsequent index searches. It may be advisable to reindex all GiST indexes after installing this update. * Prevent de-duplication of btree index entries for interval columns There are interval values that are distinguishable but compare equal, for example 24:00:00 and 1 day. This breaks assumptions made by btree de-duplication, so interval columns need to be excluded from de-duplication. This oversight can cause incorrect results from index-only scans. Moreover, after updating amcheck will report an error for almost all such indexes. Users should reindex any btree indexes on interval columns. * Rebase debian/patches/libpgport-pkglibdir. -- Christoph Berg Tue, 07 Nov 2023 14:36:06 +0100 postgresql-15 (15.4-0+deb12u1) bookworm; urgency=medium * New upstream version. + Disallow substituting a schema or owner name into an extension script if the name contains a quote, backslash, or dollar sign (Noah Misch) This restriction guards against SQL-injection hazards for trusted extensions. The PostgreSQL Project thanks Micah Gate, Valerie Woolard, Tim Carey-Smith, and Christoph Berg for reporting this problem. (CVE-2023-39417) + Fix MERGE to enforce row security policies properly (Dean Rasheed) When MERGE performs an UPDATE action, it should enforce any UPDATE or SELECT RLS policies defined on the target table, to be consistent with the way that a plain UPDATE with a WHERE clause works. Instead it was enforcing INSERT RLS policies for both INSERT and UPDATE actions. In addition, when MERGE performs a DO NOTHING action, it applied the target table's DELETE RLS policies to existing rows, even though those rows are not being deleted. While it's not a security problem, this could result in unwanted errors. The PostgreSQL Project thanks Dean Rasheed for reporting this problem.

This could allow any user having permission to create a schema to hijack the privileges of a security definer function or extension script. + Enforce row-level security policies correctly after inlining a set-returning function (Report by Wolfgang Walther, CVE-2023-2455) If a set-returning SQL-language function refers to a table having row-level security policies, and it can be inlined into a calling query, those RLS policies would not get enforced properly in some cases involving re-using a cached plan under a different role. This could allow a user to see or modify rows that should have been invisible. -- Christoph Berg Tue, 09 May 2023 19:05:02 +0200 postgresql-15 (15.2-2) unstable; urgency=medium * Add Romanian debconf translation, mulțumesc Remus-Gabriel Chelu! * Fix update-alternatives when doc package is installed stand-alone. -- Christoph Berg Mon, 27 Feb 2023 10:30:23 +0100 postgresql-15 (15.2-1) unstable; urgency=medium * New upstream version. + 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.
