Description

Two security issues were found in Samba, a SMB/CIFS file, print, and login server :

  • CVE-2013-4408 It was discovered that multiple buffer overflows in the processing of DCE-RPC packets may lead to the execution of arbitrary code.

  • CVE-2013-4475 Hemanth Thummala discovered that ACLs were not checked when opening files with alternate data streams. This issue is only exploitable if the VFS modules vfs_streams_depot and/or vfs_streams_xattr are used.
