The reply_sesssetup_and_X_spnego function in sesssetup.c in smbd in Samba before 3.4.8 and 3.5.x before 3.5.2 allows remote attackers to trigger an out-of-bounds read, and cause a denial of service (process crash), via a \xff\xff security blob length in a Session Setup AndX request.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The reply_sesssetup_and_X_spnego function in sesssetup.c in smbd in Samba before 3.4.8 and 3.5.x before
    3.5.2 allows remote attackers to trigger an out-of-bounds read, and cause a denial of service (process
    crash), via a \xff\xff security blob length in a Session Setup AndX request. (CVE-2010-1642)

The remote host is affected by the vulnerability described in GLSA-201206-22 (Samba: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Samba. Please review       the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could possibly execute arbitrary code with root       privileges, cause a Denial of Service condition, take ownership of shared       files, or bypass file permissions. Furthermore, a local attacker may be       able to cause a Denial of Service condition or obtain sensitive       information in a Samba credentials file.
  Workaround :

    There is no known workaround at this time.

Multiple vulnerabilities has been discovered and corrected in samba :

The chain_reply function in process.c in smbd in Samba before 3.4.8 and 3.5.x before 3.5.2 allows remote attackers to cause a denial of service (NULL pointer dereference and process crash) via a Negotiate Protocol request with a certain 0x0003 field value followed by a Session Setup AndX request with a certain 0x8003 field value (CVE-2010-1635).

The reply_sesssetup_and_X_spnego function in sesssetup.c in smbd in Samba before 3.4.8 and 3.5.x before 3.5.2 allows remote attackers to trigger an out-of-bounds read, and cause a denial of service (process crash), via a \xff\xff security blob length in a Session Setup AndX request (CVE-2010-1642).

The updated packages provides samba 3.4.8 which is not vulnerable to these issues.

According to its banner, the version of Samba installed on the remote host is a version of 3.4 before 3.4.8 or 3.5 < 3.5.2. Such versions are affected by two denial of service vulnerabilities that can be triggered via either a NULL pointer dereference or an uninitialized variable read.

By sending specially crafted 'Session Setup AndX' requests, an unauthenticated, remote attacker can exploit these vulnerabilities to crash the affected service, thereby denying service to legitimate users.

According to its banner, the version of Samba Server on the remote host is potentially affected by a flaw which would allow a remote attacker to disable the service.  An attacker, exploiting this flaw, would need network access to the SAMBA server.
