SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral vulnerabilities have been discovered in PostgreSQL, a database server. The Common Vulnerabilities and Exposures project identifies the following problems :
It was discovered that PostgreSQL did not properly verify the Common Name attribute in X.509 certificates, enabling attackers to bypass the (optional) TLS protection on client-server connections, by relying on a certificate from a trusted CA which contains an embedded NUL byte in the Common Name (CVE-2009-4034 ).
Authenticated database users could elevate their privileges by creating specially crafted index functions (CVE-2009-4136 ).
The following matrix shows fixed source package versions for the respective distributions.
