CVSS v3.1
Official Description
Stack-based buffer overflow in the chkNum function in lib/cgraph/scan.l in Graphviz 2.34.0 allows remote attackers to have unspecified impact via vectors related to a "badly formed number" and a "long digit list."
Technical Analysis
CVE-2014-1236 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
