File Descriptor Range Check Vulnerability in Samba

CVE-2011-0719 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
