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.
