netpbm/netpbm-security2.patch
Petr Gajdos 20145d3c7b - updated to 10.35.80: 
* asciitopgm: fix bug: memory corruption on too-long lines.
  * asciitopgm: fix bug: improper handling of blank lines.
  * pngtopnm: fix bug: -verbose reports history chunk present when
              it's really a palette.
  * bmptopnm: Don't crash on invalid zero value of image height in
              the BMP header of a compressed file.
  * bmptopnm: don't crash on large invalid value of 'colorsused' in
              the BMP header.
  * ilbmtoppm: Don't crash on image that has a transparent color
              index, but no color map.
