TITLE:
Samba Denial of Service and Format String Vulnerability

SECUNIA ADVISORY ID:
SA24046

VERIFY ADVISORY:
http://secunia.com/advisories/24046/

CRITICAL:
Moderately critical

IMPACT:
DoS, System access

WHERE:
>From local network

SOFTWARE:
Samba 3.x
http://secunia.com/product/2999/

DESCRIPTION:
Some vulnerabilities have been reported in Samba, which can be
exploited by malicious users to cause a DoS (Denial of Service) or
potentially compromise a vulnerable system.

1) Under certain conditions, smbd fails to remove requests from the
deferred file open queue. This can be exploited to cause a DoS due to
heavy resource usage by triggering an infinite loop when renaming a
file under special circumstances.

2) Samba uses filenames as format string parameter in a call to
"sprintf()" when setting Windows NT Access Control Lists using the
afsacl.so VFS plugin. This can potentially be exploited to execute
arbitrary code.

Successful exploitation requires that an AFS file system is shared to
CIFS clients using the afsacl.so VFS module and that the attacker has
write access to the share.

SOLUTION:
Update to version 3.0.24.

PROVIDED AND/OR DISCOVERED BY:
1) Reported by the vendor.
2) The vendor credits zybadawg333.
