Mandriva Linux Security Advisory MDVSA-2013:106
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : nss-pam-ldapd
Date : April 10, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated nss-pam-ldapd packages fixes the following security
vulnerability:

Garth Mollett discovered that a file descriptor overflow issue in
the use of FD_SET() in nss-pam-ldapd can lead to a stack-based buffer
overflow. An attacker could, under some circumstances, use this flaw
to cause a process that has the NSS or PAM module loaded to crash or
potentially execute arbitrary code.

The issue can be triggered in a network daemon by opening a large
number of connections and forcing a name lookup. This would result
in a crash and possibly remote code execution. This issue may also
allow local privilege escalation if a suid program does name lookups
and doesn't close file descriptors inherited from the parent process
(CVE-2013-0288).
