CVE-2011-1140

31
FAUCET Score

CVE-2011-1140 describes multiple stack consumption vulnerabilities in Wireshark versions 1.0.x, 1.2.0-1.2.14, and 1.4.0-1.4.3. These flaws, specifically in the dissect_ms_compressed_string and dissect_mscldap_string functions, allow remote attackers to trigger an infinite recursion and cause a denial of service (DoS) via specially crafted SMB or Connection-less LDAP (CLDAP) packets. The vulnerability has a CVSS score of 4.3, indicating a medium attack complexity and a potential for partial availability impact. While not actively exploited in the wild and not on the KEV catalog, a Metasploit module exists for the CLDAP dissector DoS, and it has a high FAUCET Risk Score of 95/100, despite minimal community discussion or media coverage.
