high Nessus Plugin ID 65812
New! Plugin Severity Now Using CVSS v3

The remote Debian host is missing a security-related update.


A vulnerability was discovered in PostgreSQL database server. Random numbers generated by contrib/pgcrypto functions may be easy for another database user to guess.


Upgrade the postgresql-8.4 packages.

For the stable distribution (squeeze), this problem has been fixed in version 8.4.17-0squeeze1.

Note: postgresql-8.4 in Squeeze is not affected by CVE-2013-1899 (database files corruption) and CVE-2013-1901 (unprivileged user can interfere with in-progress backups).
