Package        : libpng
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2010-1205 CVE-2010-2249
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-2010-1205

    It was discovered a buffer overflow in libpng which allows remote
    attackers to execute arbitrary code via a PNG image that triggers 
    an additional data row.


CVE-2010-2249

    It was discovered a memory leak in libpng which allows remote
    attackers to cause a denial of service (memory consumption and
    application crash) via a PNG image containing malformed Physical
    Scale (aka sCAL) chunks


For the stable distribution (lenny), these problems have been fixed in
version 1.2.27-2+lenny4.

For the testing (squeeze) and unstable (sid) distribution, these
problems have been fixed in version 1.2.44-1

We recommend that you upgrade your libpng package.
