PACKAGE   : mod_auth_pgsql
SUMMARY   : Remote vulnerability allows an attacker to bypass authentication
DATE      : 2001-09-28 11:26:00
ID        : CLA-2001:427

DESCRIPTION
 "mod_auth_mysql" is an authentication module for apache which
 authenticates users against a PostgreSQL database.
 RUS-CERT discovered a vulnerability[1][3] in several Apache
 authentication modules which use SQL databases to retrieve user
 information. This vulnerability allows a remote attacker to change
 the query that the module sends to the SQL server and circumvent the
 authentication process.
 This vulnerability is *still* present in the 0.9.6 version in a
 slightly different fashion:
 
 Username: '';; select ''bla
 Password: bla
 
 The author has been notified and released version 0.9.9 on Sep 25th
 to address this problem[2].
 Additionally, this is also a bugfix update for this package, which
 wasn't linked against the PostgreSQL libraries in our previous
 releases.


SOLUTION
 It is recommended that all mod_auth_pgsql users upgrade the package.
 All versions released here, even being older, have patches to address
 this problem. The update for the 0.8 version also contains the
 snprintf() patches from Erik Rossen.
 
 IMPORTANT: it is necessary to restart the Apache web server after
 updating these packages.
