Details

Mitsumasa Kondo and Kyotaro Horiguchi discovered that PostgreSQL
incorrectly handled certain connection requests containing database names
starting with a dash. A remote attacker could use this flaw to damage or
destroy files within a server’s data directory. This issue only applied to
Ubuntu 11.10, Ubuntu 12.04 LTS, and Ubuntu 12.10. (CVE-2013-1899)

Marko Kreen discovered that PostgreSQL incorrectly generated random
numbers. An authenticated attacker could use this flaw to possibly guess
another database user’s random numbers. (CVE-2013-1900)

Noah Misch discovered that PostgreSQL incorrectly handled certain privilege
checks. An unprivileged attacker could use this flaw to possibly interfere
with in-progress backups. This issue only applied to Ubuntu 11.10,
Ubuntu 12.04 LTS, and Ubuntu 12.10. (CVE-2013-1901)
