|Bugzilla:||795509: CVE-2012-0870 samba: Any Batched ("AndX") request processing infinite recursion and heap-based buffer overflow|
The MITRE CVE dictionary describes this issue as:
Heap-based buffer overflow in process.c in smbd in Samba 3.0, as used in the file-sharing service on the BlackBerry PlayBook tablet before 22.214.171.12471 and other products, allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a Batched (aka AndX) request that triggers infinite recursion.
This issue did not affect samba3x packages as shipped with Red Hat Enterprise Linux 5 and samba packages as shipped with Red Hat Enterprise Linux 6, as it only affected Samba versions prior to 3.4.0. This issue was addressed in samba packages in Red Hat Enterprise Linux 4 and 5 via RHSA-2012:0332.
