Mandriva Linux Security Advisory : postgresql (MDVSA-2010:103)

high Nessus Plugin ID 46690


New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Mandriva Linux host is missing one or more security updates.


Multiple vulnerabilities was discovered and corrected in postgresql :

The bitsubstr function in backend/utils/adt/varbit.c in PostgreSQL 8.0.23, 8.1.11, and 8.3.8 allows remote authenticated users to cause a denial of service (daemon crash) or have unspecified other impact via vectors involving a negative integer in the third argument, as demonstrated by a SELECT statement that contains a call to the substring function for a bit string, related to an overflow.

A flaw was found in the way the PostgreSQL server process enforced permission checks on scripts written in PL/Perl. A remote, authenticated user, running a specially crafted PL/Perl script, could use this flaw to bypass PL/Perl trusted mode restrictions, allowing them to obtain sensitive information; execute arbitrary Perl scripts;
or cause a denial of service (remove protected, sensitive data) (CVE-2010-1169).

The PL/Tcl implementation in PostgreSQL 7.4 before 7.4.29, 8.0 before 8.0.25, 8.1 before 8.1.21, 8.2 before 8.2.17, 8.3 before 8.3.11, 8.4 before 8.4.4, and 9.0 Beta before 9.0 Beta 2 loads Tcl code from the pltcl_modules table regardless of the table's ownership and permissions, which allows remote authenticated users, with database-creation privileges, to execute arbitrary Tcl code by creating this table and inserting a crafted Tcl script (CVE-2010-1170).

PostgreSQL 7.4 before 7.4.29, 8.0 before 8.0.25, 8.1 before 8.1.21, 8.2 before 8.2.17, 8.3 before 8.3.11, and 8.4 before 8.4.4 does not properly check privileges during certain RESET ALL operations, which allows remote authenticated users to remove arbitrary parameter settings via a (1) ALTER USER or (2) ALTER DATABASE statement (CVE-2010-1975).
