Scientific Linux Security Update : samba and samba3x on SL5.x, SL6.x i386/srpm/x86_64
Low Nessus Plugin ID 76449
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionA denial of service flaw was found in the way the sys_recvfile() function of nmbd, the NetBIOS message block daemon, processed non-blocking sockets. An attacker could send a specially crafted packet that, when processed, would cause nmbd to enter an infinite loop and consume an excessive amount of CPU time. (CVE-2014-0244)
It was discovered that smbd, the Samba file server daemon, did not properly handle certain files that were stored on the disk and used a valid Unicode character in the file name. An attacker able to send an authenticated non-Unicode request that attempted to read such a file could cause smbd to crash. (CVE-2014-3493)
After installing this update, the smb service will be restarted automatically.
SolutionUpdate the affected packages.
