The Treck TCP/IP stack before 6.0.1.66 improperly handles an IPv4/ICMPv4 Length Parameter Inconsistency, which might allow remote attackers to trigger an information leak.
AnalysisAI
The Treck TCP/IP stack before 6.0.1.66 improperly handles an IPv4/ICMPv4 Length Parameter Inconsistency, which might allow remote attackers to trigger an information leak. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
Technical ContextAI
This vulnerability is classified as Buffer Overflow (CWE-119), which allows attackers to corrupt memory to execute arbitrary code or crash the application. The Treck TCP/IP stack before 6.0.1.66 improperly handles an IPv4/ICMPv4 Length Parameter Inconsistency, which might allow remote attackers to trigger an information leak. Affected products include: Treck Tcp\/Ip. Version information: before 6.0.1.66.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Use memory-safe languages or bounds-checking. Enable ASLR, DEP/NX, stack canaries. Use safe string functions.
