Synopsis: Moderate: postgresql security update
Advisory ID: SLSA-2015:1194-1
Issue Date: 2015-06-29
CVE Numbers: CVE-2015-3165
 CVE-2015-3166
 CVE-2015-3167
--

A double-free flaw was found in the connection handling. An
unauthenticated attacker could exploit this flaw to crash the PostgreSQL
back end by disconnecting at approximately the same time as the
authentication time out is triggered. (CVE-2015-3165)

It was discovered that PostgreSQL did not properly check the return values
of certain standard library functions. If the system is in a state that
would cause the standard library functions to fail, for example memory
exhaustion, an authenticated user could exploit this flaw to disclose
partial memory contents or cause the GSSAPI authentication to use an
incorrect keytab file. (CVE-2015-3166)

It was discovered that the pgcrypto module could return different error
messages when decrypting certain data with an incorrect key. This can help
an authenticated user to launch a possible cryptographic attack, although
no suitable attack is currently known. (CVE-2015-3167)

If the postgresql service is running, it will be automatically restarted
after installing this update.
