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

Description Martin Prpič 2015-05-14 10:18:55 UTC 
The PostgreSQL project reports the following issue:

The server regularly ignores the return value of certain standard library functions, such as sprintf() and putenv(), which can fail under memory exhaustion. This could, in principle, have a variety of security-relevant effects. For example, an unnoticed sprintf() error could permit disclosure of prior buffer contents. A particular putenv() failure could cause GSSAPI authentication to consult the wrong keytab file. Reducing such exploits to practice is expected to be impossible in most configurations, given the requirement for such an intricate coincidence of system state.

This flaw is fixed in upstream versions 9.4.2, 9.3.7, 9.2.11, 9.1.16, and 9.0.20 of PostgreSQL.
