It is used by several programs, including web browsers and potentially server processes. </p> </background> <description> <p>The png_push_read_chunk function in pngpread.c in the progressive decoder enters an infinite loop, when it encounters a zero-length IDAT chunk. In addition certain integer overflows have been detected and corrected. </p> <p>The 1.2 branch is not affected by these vulnerabilities.</p> </description> <impact type="normal"> <p>A remote attacker could entice a user to open a specially crafted PNG file using an application linked against libpng, possibly resulting in Denial of Service. </p> </impact> <workaround> <p>There is no known workaround at this time.</p> </workaround> <resolution> <p>All libpng users should upgrade to the latest version:</p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libpng-1.6.10" </code> <p>Users with current installs in the 1.5 branch should also upgrade this using:</p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/libpng-1.5.18:1.5" </code> <p>Packages which depend on this library may need to be recompiled. Tools such as revdep-rebuild may assist in identifying these packages. </p> </resolution> <references> <uri link="http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-7353";> CVE-2013-7353 </uri> <uri link="http://nvd.nist.gov/nvd.cfm?cvename=CVE-2013-7354";> CVE-2013-7354 </uri> <uri link="http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0333";> CVE-2014-0333 </uri> </references> <metadata tag="requester" timestamp="Thu, 15 May 2014 04:38:43 +0000"> BlueKnight </metadata> <metadata tag="submitter" timestamp="Thu, 14 Aug 2014 13:52:46 +0000"> pinkbyte </metadata> </glsa>
