nss-pam-ldapd FD_SETSIZE buffer overflow
|nsspamldapd-fdsetsize-bo (82175)||High Risk|
nss-pam-ldapd is vulnerable to a stack-based buffer overflow, caused by an array indexing error when handling FD_SETSIZE macro. A remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
Upgrade to the latest version of nss-pam-ldapd (0.7.18 or 0.8.11 or later), available from the Arthur de Jong Web site. See References.

- CVE-2013-0288: nss-pam-ldapd before 0.7.18 and 0.8.x before 0.8.11 allows context-dependent attackers to cause a denial of service (application crash) and possibly execute arbitrary code by performing a name lookup on an application with a large number of open file descriptors, which triggers a stack-based buffer overflow related to incorrect use of the FD_SET macro.
