SecurityAlert : 4217 CVE : CVE-2008-3908 CWE : CWE-119 SecurityRisk : High  (About) Remote Exploit : Yes Local Exploit : No Victim interaction required : No Exploit Available : No Credit : Rob Holland Published : 06.09.2008
Advisory Content : 2008/08/25 #2008-014 WordNet stack and heap overflows Description: The WordNet 3.0 Unix library and command-line interface suffer from a number of stack overflows due to their handling of command line arguments, environment variables and data read from user supplied dictionaries. The oCERT team was contacted by Moritz Muehlenhoff from the Debian project requesting an audit of the WordNet code base. These vulnerabilities were the findings of the requested audit. Stack overflows fed via the command line, environment variables or WordNet library calls can result in arbitrary code execution. Stack and heap overflows via modified WordNet dictionaries may allow arbitrary code execution. It should be noted that despite the ease with which arbitrary code can be executed via these WordNet flaws, unless WordNet is being used by a daemon or web service running as a user other than that of the attacker, this is unlikely to result in privilege escalation or the ability to take any action not already possible as the attacking user. The following patch fixes the issues: http://www.ocert.org/analysis/2008-014/wordnet.patch Affected version: WordNet = 3.0 Fixed version: Princeton unfortunately lack the resources to produce a new release of this code and will therefore not be releasing a new version as a result of this audit.
