netpbm-free - buffer overflows

Greg Roelofs discovered and fixed several buffer overflows in pnmtopng
which is also included in netpbm, a collection of graphic conversion
utilities, that can lead to the execution of arbitrary code via a
specially crafted PNM file.

For the oldstable distribution (woody) these problems have been fixed in
version 9.20-8.5.

For the stable distribution (sarge) these problems have been fixed in
version 10.0-8sarge2.

For the unstable distribution (sid) these problems will be fixed in
version 10.0-11.

We recommend that you upgrade your netpbm package.
