Last modified

CVE-2011-0719 is a vulnerability of currently unknown severity. Samba 3.x before 3.3.15, 3.4.x before 3.4.12, and 3.5.x before 3.5.7 does not perform range checks for file descriptors before use of the FD_SET macro, which allows remote attackers to cause a denial of service (stack memory corruption, and infinite loop or daemon crash) by opening a large number of files, related to (1) Winbind or (2) smbd.. EPSS estimates a 4.65% chance of exploitation in the next 30 days.
