tag_insight = "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 when applications use pthreads.

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

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

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

For the unstable distribution (sid), this problem has been fixed in
version 256-1.

We recommend that you upgrade your libnss-ldap package.";
