Package : libpng
Vulnerability : several
Problem type : local (remote)
Debian-specific: no
CVE Id(s) : CVE-2009-2042 CVE-2010-0205
Debian Bugs : 533676 572308


Several vulnerabilities have been discovered in libpng, a library for
reading and writing PNG files. The Common Vulnerabilities and
Exposures project identifies the following problems:

CVE-2009-2042

libpng 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.


CVE-2010-0205

libpng 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


For the stable distribution (lenny), these problems have been fixed in
version 1.2.27-2+lenny3.

For the testing (squeeze) and unstable (sid) distribution, these
problems have been fixed in version 1.2.43-1

We recommend that you upgrade your libpng package.
