CVE-2011-0719

CVE-2011-0719 describes a denial-of-service vulnerability in Samba versions 3.x before 3.3.15, 3.4.x before 3.4.12, and 3.5.x before 3.5.7. This flaw stems from a lack of range checks for file descriptors before using the FD_SET macro, allowing remote attackers to trigger stack memory corruption and an infinite loop or daemon crash by opening numerous files. With a CVSS score of 5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P), it is a medium-severity vulnerability that can be exploited remotely with low attack complexity, leading to a partial denial of service. There is no evidence of active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
