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 via a Negotiate Protocol request with a certain 0x0003 field value followed by a Session Setup AndX request with a certain 0x8003 field value . 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 , via a \xff\xff security blob length in a Session Setup AndX request . The updated packages provides samba 3.4.8 which is not vulnerable to these issues.
