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).
