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.");
