    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.
