postgresql-8.4 (8.4.17-0ubuntu10.04) lucid-security; urgency=low
* New upstream security/bug fix release: (LP: #1163184)
- Reset OpenSSL randomness state in each postmaster child process.
This avoids a scenario wherein random numbers generated by
"contrib/pgcrypto" functions might be relatively easy for another
database user to guess. The risk is only significant when the
postmaster is configured with ssl = on but most connections don't
use SSL encryption. [CVE-2013-1900]
- Fix GiST indexes to not use "fuzzy" geometric comparisons when it's
not appropriate to do so.
The core geometric types perform comparisons using "fuzzy"
equality, but gist_box_same must do exact comparisons, else GiST
indexes using it might become inconsistent. After installing this
update, users should "REINDEX" any GiST indexes on box, polygon,
circle, or point columns, since all of these use gist_box_same.
- Fix erroneous range-union and penalty logic in GiST indexes that
use "contrib/btree_gist" for variable-width data types, that is
text, bytea, bit, and numeric columns.
These errors could result in inconsistent indexes in which some
keys that are present would not be found by searches, and also in
useless index bloat. Users are advised to "REINDEX" such indexes
after installing this update.
- Fix bugs in GiST page splitting code for multi-column indexes.
These errors could result in inconsistent indexes in which some
keys that are present would not be found by searches, and also in
indexes that are unnecessarily inefficient to search. Users are
advised to "REINDEX" multi-column GiST indexes after installing
this update.
- See HISTORY/changelog.gz for the other bug fixes.
