Summary

Samba is prone to multiple vulnerabilities.

Insight

Insight

- CVE-2007-0452: Internally Samba's file server daemon, smbd, implements support for deferred file open calls in an attempt to serve client requests that would otherwise fail due to a share mode violation. When renaming a file under certain circumstances it is possible that the request is never removed from the deferred open queue. smbd will then become stuck is a loop trying to service the open request. This bug may allow an authenticated user to exhaust resources such as memory and CPU on the server by opening multiple CIFS sessions, each of which will normally spawn a new smbd process, and sending each connection into an infinite loop. - CVE-2007-0454: NOTE: This security advisory only impacts Samba servers that share AFS file systems to CIFS clients and which have been explicitly instructed in smb.conf to load the afsacl.so VFS module. The source defect results in the name of a file stored on disk being used as the format string in a call to snprintf(). This bug becomes exploitable only when a user is able to write to a share which utilizes Samba's afsacl.so library for setting Windows NT access control lists on files residing on an AFS file system.
