CVE-2013-6954: Null Pointer Dereference

First published: Thu Dec 19 2013(Updated: )

libpng 1.6.8 was released [1] and notes the following fix: Handle zero-length PLTE chunk or NULL palette with png_error() instead of png_chunk_report(), which by default issues a warning rather than an error, leading to later reading from a NULL pointer (png_ptr-&gt;palette) in png_do_expand_palette(). This is <a href="https://access.redhat.com/security/cve/CVE-2013-6954">CVE-2013-6954</a> and VU#650142. The git commit to fix is available [3].
