Garth Mollett discovered that a file descriptor overflow issue in the use of FD_SET() in nss-pam-ldapd, which provides NSS and PAM modules for using LDAP as a naming service, 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. For the stable distribution (squeeze) this problem has been fixed in version 0.7.15+squeeze4. For the testing distribution (wheezy), this problem has been fixed in version 0.8.10-3. For the unstable distribution (sid), this problem has been fixed in version 0.8.10-3. We recommend that you upgrade your nss-pam-ldapd packages.
