Description

Several vulnerabilities have been found in PostgreSQL-9.4, a SQL database system.

CVE-2015-3165

(Remote crash)

SSL clients disconnecting just before the authentication timeout expires can cause the server to crash.

CVE-2015-3166

(Information exposure)

The replacement implementation of snprintf() failed to check for errors reported by the underlying system library calls; the main case that might be missed is out-of-memory situations. In the worst case this might lead to information exposure.

CVE-2015-3167

(Possible side-channel key exposure)

In contrib/pgcrypto, some cases of decryption with an incorrect key could report other error message texts. Fix by using a one-size-fits-all message.
