Mandriva Linux Security Advisory : samba (MDVSA-2010:141)
Medium Nessus Plugin ID 48199
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionMultiple 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.
SolutionUpdate the affected packages.
