    Package : postgresql-9.1
    CVE ID : CVE-2015-5288 CVE-2016-0766 CVE-2016-0773

    Several vulnerabilities have been found in PostgreSQL-9.1, a SQL
    database system.

    CVE-2015-5288

    Josh Kupershmidt discovered a vulnerability in the crypt() function
    in the pgCrypto extension. Certain invalid salt arguments can cause
    the server to crash or to disclose a few bytes of server memory.

    CVE-2016-0766

    A privilege escalation vulnerability for users of PL/Java was
    discovered. Certain custom configuration settings (GUCs) for PL/Java
    will now be modifiable only by the database superuser to mitigate
    this issue.

    CVE-2016-0773

    Tom Lane and Greg Stark discovered a flaw in the way PostgreSQL
    processes specially crafted regular expressions. Very large
    character ranges in bracket expressions could cause infinite
    loops or memory overwrites. A remote attacker can exploit this
    flaw to cause a denial of service or, potentially, to execute
    arbitrary code.

    For the oldstable distribution (wheezy), these problems have been fixed
    in version 9.1.20-0+deb7u1.

    We recommend that you upgrade your postgresql-9.1 packages.
