Synopsis
PostgreSQL contains multiple vulnerabilities that could result in privilege escalation or a Denial of Service.Background
PostgreSQL is an open source object-relational database management system.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| dev-db/postgresql | < 8.0.15 | >= 8.0.15 | All supported architectures |
Description
If using the "expression indexes" feature, PostgreSQL executes index functions as the superuser during VACUUM and ANALYZE instead of the table owner, and allows SET ROLE and SET SESSION AUTHORIZATION in the index functions (CVE-2007-6600). Additionally, several errors involving regular expressions were found (CVE-2007-4769, CVE-2007-4772, CVE-2007-6067). Eventually, a privilege escalation vulnerability via unspecified vectors in the DBLink module was reported (CVE-2007-6601). This vulnerability is exploitable when local trust or ident authentication is used, and is due to an incomplete fix of CVE-2007-3278.
Impact
A remote authenticated attacker could send specially crafted queries containing complex regular expressions to the server that could result in a Denial of Service by a server crash (CVE-2007-4769), an infinite loop (CVE-2007-4772) or a memory exhaustion (CVE-2007-6067). The two other vulnerabilities can be exploited to gain additional privileges.
Workaround
There is no known workaround for all these issues at this time.
Resolution
All PostgreSQL users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "dev-db/postgresql"
