                 Mandrakelinux Security Update Advisory
 _______________________________________________________________________

 Package name:           libpng
 Advisory ID:            MDKSA-2004:063
 Date:                   June 29th, 2004

 Affected versions:	 10.0, 9.1, 9.2, Corporate Server 2.1,
			 Multi Network Firewall 8.2
 ______________________________________________________________________

 Problem Description:

 A buffer overflow vulnerability was discovered in libpng due to a wrong
 calculation of some loop offset values. This buffer overflow can lead
 to Denial of Service or even remote compromise.
 
 This vulnerability was initially patched in January of 2003, but it
 has since been noted that fixes were required in two additional places
 that had not been corrected with the earlier patch.  This update uses
 an updated patch to fix all known issues.
 
 After the upgrade, all applications that use libpng should be
 restarted.  Many applications are linked to libpng, so if you are
 unsure of what applications to restart, you may wish to reboot the
 system. Mandrakesoft encourages all users to upgrade immediately.
