Peachtree Linux Security Notice PLSN-0004
April 20, 2005

Buffer overflow in PL/PGSQL parser allowing database users to run arbitrary
code as pgsql user
CAN-2005-0245, CAN-2005-0247
---------------------------------------------------------------------------

The following Peachtree Linux releases are affected:

Peachtree Linux release 1 ("Atlanta")

Description:

CAN-2005-0245, CAN-2005-0247: Two buffer overflow vulnerabilities are
present in the PL/PGSL parser gram.y which allow anyone with the ability
to run SQL statements to execute arbitrary code as the pgsql user.

Packages:

alpha
1e36e9d2d64e9ff7a85c99a539ab1f61 postgresql-7.4.7.alpha.dist

i386
430f9cc3b162bba75bb970e288c80dac postgresql-7.4.7.i686.dist

ppc
9e805d9a73becf8da6910ac493bb37a1 postgresql-7.4.7.ppc.dist

Solution:

Download the appropriate package for your release of Peachtree linux.
Upgrade your system to the new package:

distadd -u packagename

Where package name is the name of the package file from the list above.

After installation of the new package, restart any running postgresql
services. This new version of postgresql does not change the layout of
the database on the filesystem, and therefore does not require a
dump/restore.
