Vulnerability Assessment Details
Check for the version of the postgresql packages
Detailed Explanation for this Vulnerability Assessment
Updated postresql packages that correct various security issues are now
available for Red Hat Enterprise Linux 4.
This update has been rated as having important security impact by the Red
Hat Security Response Team.
A flaw in the LOAD command in PostgreSQL was discovered. A local user
could use this flaw to load arbitrary shared libraries and therefore
execute arbitrary code, gaining the rights of the PostgreSQL server.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2005-0227 to this issue.
A permission checking flaw in PostgreSQL was discovered. A local user
could bypass the EXECUTE permission check for functions by using the CREATE
AGGREGATE command. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2005-0244 to this issue.
Multiple buffer overflows were found in PL/PgSQL. A database user who has
permissions to create plpgsql functions could trigger this flaw which could
lead to arbitrary code execution, gaining the rights of the PostgreSQL
server. The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the names CVE-2005-0245 and CVE-2005-0247 to these issues.
A flaw in the integer aggregator (intagg) contrib module for PostgreSQL was
found. A user could create carefully crafted arrays and cause a denial of
service (crash). The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2005-0246 to this issue.
The update also fixes some minor problems, notably conflicts with SELinux.
Users of postgresql should update to these erratum packages that contain
patches and are not vulnerable to these issues.
