Debian DSA-1430-1 : libnss-ldap - denial of service

medium Nessus Plugin ID 29338

Synopsis

The remote Debian host is missing a security-related update.

Description

It was reported that a race condition exists in libnss-ldap, an NSS module for using LDAP as a naming service, which could cause denial of service attacks if applications use pthreads.

This problem was spotted in the dovecot IMAP/POP server but potentially affects more programs.

Solution

Upgrade the libnss-ldap package.

For the old stable distribution (sarge), this problem has been fixed in version 238-1sarge1.

For the stable distribution (etch), this problem has been fixed in version 251-7.5etch1.
