Debian DSA-1463-1 : postgresql-7.4 - several vulnerabilities

high Nessus Plugin ID 29968

Synopsis

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

Description

Several local vulnerabilities have been discovered in PostgreSQL, an object-relational SQL database. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2007-3278 It was discovered that the DBLink module performed insufficient credential validation. This issue is also tracked as CVE-2007-6601, since the initial upstream fix was incomplete.

- CVE-2007-4769 Tavis Ormandy and Will Drewry discovered that a bug in the handling of back-references inside the regular expressions engine could lead to an out of bounds read, resulting in a crash. This constitutes only a security problem if an application using PostgreSQL processes regular expressions from untrusted sources.

- CVE-2007-4772 Tavis Ormandy and Will Drewry discovered that the optimizer for regular expression could be tricked into an infinite loop, resulting in denial of service. This constitutes only a security problem if an application using PostgreSQL processes regular expressions from untrusted sources.

- CVE-2007-6067 Tavis Ormandy and Will Drewry discovered that the optimizer for regular expression could be tricked massive resource consumption. This constitutes only a security problem if an application using PostgreSQL processes regular expressions from untrusted sources.

- CVE-2007-6600 Functions in index expressions could lead to privilege escalation. For a more in depth explanation please see the upstream announce available at http://www.postgresql.org/about/news.905.

Solution

Upgrade the postgresql-7.4 packages.

For the old stable distribution (sarge), some of these problems have been fixed in version 7.4.7-6sarge6 of the postgresql package. Please note that the fix for CVE-2007-6600 and for the handling of regular expressions havn't been backported due to the intrusiveness of the fix. We recommend to upgrade to the stable distribution if these vulnerabilities affect your setup.

For the stable distribution (etch), these problems have been fixed in version 7.4.19-0etch1.
