"A flaw was discovered in the pdf_load_mesh_params() function allowing
out-of-bounds write access to memory locations. With carefully crafted
input, that could trigger a heap overflow, resulting in application
crash or possibly having other unspecified impact.

For Debian 7 'Wheezy', these problems have been fixed in version
0.9-2+deb7u3.

We recommend that you upgrade your mupdf packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
