- ------------------------------------------------------------------------ Debian Security Advisory DSA-2072-1 security@debian.org http://www.debian.org/security/ Giuseppe Iuculano July 19, 2010 http://www.debian.org/security/faq - ------------------------------------------------------------------------
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.
Upgrade instructions - --------------------
wget url will fetch the file for you dpkg -i file.deb will install the referenced file.
