Description
This security bulletin contains information about 1 vulnerability.
1) Buffer overflow (CVE-ID: CVE-2011-0719)
CWE-ID: CWE-119 - Memory corruption
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N]
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
