+ <background>
+ <p>libpng is a standard library used to process PNG (Portable Network
+ Graphics) images. It is used by several programs, including web browsers
+ and potentially server processes.
+ </p>
+ </background>
+ <description>
+ <p>Multiple vulnerabilities were found in libpng:</p>
+
+ <ul>
+ <li>The png_decompress_chunk() function in pngrutil.c does not properly
+ handle certain type of compressed data (CVE-2010-0205)
+ </li>
+ <li>A buffer overflow in pngread.c when using progressive applications
+ (CVE-2010-1205)
+ </li>
+ <li>A memory leak in pngrutil.c when dealing with a certain type of
+ chunks (CVE-2010-2249)
+ </li>
+ </ul>
+ </description>
+ <impact type="normal">
+ <p>An attacker could exploit these vulnerabilities to cause programs linked
+ against the library to crash or execute arbitrary code with the
+ permissions of the user running the vulnerable program, which could be
+ the root user.
+ </p>
+ </impact>
+ <workaround>
+ <p>There is no known workaround at this time.</p>
+
+ </workaround>
+ <resolution>
+ <p>All libpng 1.4 users should upgrade to the latest version:</p>
+
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=media-libs/libpng-1.4.3"
+ </code>
+
+ <p>All libpng 1.2 users should upgrade to the latest version:</p>
+
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=media-libs/libpng-1.2.46"
+ </code>
