The starting offsets for the loops are calculated incorrectly which causes a buffer overrun beyond the beginning of the row buffer. For the current stable distribution (woody) this problem has been fixed in version 1.0.12-3.woody.3 for libpng and in version 1.2.1-1.1.woody.3 for libpng3. For the old stable distribution (potato) this problem has been fixed in version 1.0.5-1.1 for libpng. There are no other libpng packages. For the unstable distribution (sid) this problem has been fixed in version 1.0.12-7 for libpng and in version 1.2.5-8 for libpng3. We recommend that you upgrade your libpng packages. wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.

libpng 1.0.15 is available from sf there's an other Makefile for sparc maybe someone sparc-dev could also try this if we update to 1.0.15
Is there any good reason for keeping support for 1.0 ? I think it gave a lot of headaches a while back (should ask spider).
1.0 and 1.1 are slot'ed so they can exist together
i know its slotted, i'm not sure it should be, cause they partially overwrite eachothers files. The question was, is it still used.
glsa sent.
