For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your graphviz packages.";
tag_summary   = "Two buffer overflow vulnerabilities were reported in Graphviz, a rich
collection of graph drawing tools. The Common Vulnerabilities and
Exposures project identifies the following issues:

CVE-2014-0978 
It was discovered that user-supplied input used in the yyerror()
function in lib/cgraph/scan.l is not bound-checked before being
copied into an insufficiently sized memory buffer. A
context-dependent attacker could supply a specially crafted input
file containing a long line to cause a stack-based buffer overlow,
resulting in a denial of service (application crash) or potentially
allowing the execution of arbitrary code.

CVE-2014-1236 
Sebastian Krahmer reported an overflow condition in the chkNum()
function in lib/cgraph/scan.l that is triggered as the used regular
expression accepts an arbitrary long digit list. With a specially
crafted input file, a context-dependent attacker can cause a
stack-based buffer overflow, resulting in a denial of service
(application crash) or potentially allowing the execution of
arbitrary code.";
