  postgresql-9.1 (9.1.23-0ubuntu0.12.04) precise-security; urgency=medium

  * New upstream security/bug fix release (LP: #1614113)
    - Fix possible mis-evaluation of nested CASE-WHEN expressions
      A CASE expression appearing within the test value subexpression of
      another CASE could become confused about whether its own test value was
      null or not. Also, inlining of a SQL function implementing the equality
      operator used by a CASE expression could result in passing the wrong
      test value to functions called within a CASE expression in the SQL
      function's body. If the test values were of different data types, a
      crash might result; moreover such situations could be abused to allow
      disclosure of portions of server memory. (CVE-2016-5423)

    - Fix client programs' handling of special characters in database and role
      names
      Numerous places in vacuumdb and other client programs could become
      confused by database and role names containing double quotes or
      backslashes. Tighten up quoting rules to make that safe. Also, ensure
      that when a conninfo string is used as a database name parameter to
      these programs, it is correctly treated as such throughout.

      Fix handling of paired double quotes in psql's \connect and \password
      commands to match the documentation.

      Introduce a new -reuse-previous option in psql's \connect command to
      allow explicit control of whether to re-use connection parameters from a
      previous connection. (Without this, the choice is based on whether the
      database name looks like a conninfo string, as before.) This allows
      secure handling of database names containing special characters in
      pg_dumpall scripts.

      pg_dumpall now refuses to deal with database and role names containing
      carriage returns or newlines, as it seems impractical to quote those
      characters safely on Windows. In future we may reject such names on the
      server side, but that step has not been taken yet.

      These are considered security fixes because crafted object names
      containing special characters could have been used to execute commands
      with superuser privileges the next time a superuser executes pg_dumpall
      or other routine maintenance operations. (CVE-2016-5424)

  postgresql-9.1 (9.1.20-0ubuntu0.12.04) precise-security; urgency=medium

  * New upstream security/bug fix release: (LP: #1544576)
    - Fix infinite loops and buffer-overrun problems in regular expressions.
      Very large character ranges in bracket expressions could cause infinite
      loops in some cases, and memory overwrites in other cases.
      (CVE-2016-0773)
    - Prevent certain PL/Java parameters from being set by non-superusers.
      This change mitigates a PL/Java security bug (CVE-2016-0766), which was
      fixed in PL/Java by marking these parameters as superuser-only. To fix
      the security hazard for sites that update PostgreSQL more frequently
      than PL/Java, make the core code aware of them also.
    - See release notes for details about other fixes.

  * New upstream security/bug fix release (LP: #1504132)
    - Fix contrib/pgcrypto to detect and report too-short crypt() salts
      Certain invalid salt arguments crashed the server or disclosed a few
      bytes of server memory. We have not ruled out the viability of attacks
      that arrange for presence of confidential information in the disclosed
      bytes, but they seem unlikely. (CVE-2015-5288)

CVE-2015-5288 vulnerable to too-short crypt() salts

Version: 9.1.16-0ubuntu0.12.04 2015-05-25 12:06:44 UTC

  postgresql-9.1 (9.1.16-0ubuntu0.12.04) precise-security; urgency=medium

  * New upstream security/bug fix release (LP: #1457093)
    - Avoid possible crash when client disconnects just before the
      authentication timeout expires.
      If the timeout interrupt fired partway through the session shutdown
      sequence, SSL-related state would be freed twice, typically causing a
      crash and hence denial of service to other sessions. Experimentation
      shows that an unauthenticated remote attacker could trigger the bug
      somewhat consistently, hence treat as security issue. (CVE-2015-3165)

    - Improve detection of system-call failures
      Our replacement implementation of snprintf() failed to check for errors
      reported by the underlying system library calls; the main case that
      might be missed is out-of-memory situations. In the worst case this
      might lead to information exposure, due to our code assuming that a
      buffer had been overwritten when it hadn't been. Also, there were a few
      places in which security-relevant calls of other system library
      functions did not check for failure.
      It remains possible that some calls of the *printf() family of functions
      are vulnerable to information disclosure if an out-of-memory error
      occurs at just the wrong time. We judge the risk to not be large, but
      will continue analysis in this area. (CVE-2015-3166)

    - In contrib/pgcrypto, uniformly report decryption failures as Wrong key
      or corrupt data
      Previously, some cases of decryption with an incorrect key could report
      other error message texts. It has been shown that such variance in
      error reports can aid attackers in recovering keys from other systems.
      While it's unknown whether pgcrypto's specific behaviors are likewise
      exploitable, it seems better to avoid the risk by using a
      one-size-fits-all message. (CVE-2015-3167)

    - Protect against wraparound of multixact member IDs
      Under certain usage patterns, the existing defenses against this might
      be insufficient, allowing pg_multixact/members files to be removed too
      early, resulting in data loss.
      The fix for this includes modifying the server to fail transactions that
      would result in overwriting old multixact member ID data, and improving
      autovacuum to ensure it will act proactively to prevent multixact member
      ID wraparound, as it does for transaction ID wraparound.

   - See release notes for details about other fixes.

  * Backport the autopkgtest, as running the postgresql-common integration
    test suite is a lot simpler that way. Add manual creation of required
    locales, as precise's postgresql-common test suite does not yet do that by
    itself.
