Changelog
libpng (1.2.27-2+lenny3) stable-security; urgency=high
* Non-maintainer upload by the Security Team.
* Fixed CVE-2009-2042: does not properly parse 1-bit interlaced images with
width values that are not divisible by 8, which causes libpng to include
uninitialized bits in certain rows of a PNG file and might allow remote
attackers to read portions of sensitive memory via "out-of-bounds pixels"
in the file (Closes: 533676)
* Fixed CVE-2010-0205: does not properly handle compressed ancillary-chunk
data that has a disproportionately large uncompressed representation, which
allows remote attackers to cause a denial of service (memory and CPU
consumption, and application hang) via a crafted PNG file (Closes: #572308)
