+ <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>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 "&gt;=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 "&gt;=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.
