Description Jan Lieskovsky 2012-03-09 05:00:32 EST
Two format string flaws were found in the way perl-DBD-Pg, a Perl language PostgreSQL DBI implementation, performed:
1) turning of database notices into appropriate Perl language warning messages,
2) preparation of particular DBD statement.

A rogue server could provide a specially-crafted database warning or specially-crafted DBD statement, which once processed by the perl-DBD-Pg interface would lead to perl-DBD-Pg based process crash.

Comment 4 Huzaifa S. Sidhpurwala 2012-07-02 04:51:46 EDT
warn() function is not protected by fortify source format string protections, 
(read bug 836931), hence assuming that format string exploitation can cause ACE
