Title:	Debian: Security Advisory (DSA-2843-1)
Summary:	The remote host is missing an update for the Debian 'graphviz' package(s) announced via the DSA-2843-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'graphviz' package(s) announced via the DSA-2843-1 advisory. Vulnerability Insight: 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 overflow, 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. For the oldstable distribution (squeeze), these problems have been fixed in version 2.26.3-5+squeeze2. For the stable distribution (wheezy), these problems have been fixed in version 2.26.3-14+deb7u1. For the unstable distribution (sid), these problems will be fixed soon. We recommend that you upgrade your graphviz packages. Affected Software/OS: 'graphviz' package(s) on Debian 6, Debian 7. Solution: Please install the updated package(s).
