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.
