Debian Security Advisory DSA-1430-1 [email protected]

- ------------------------------------------------------------------------
Package : libnss-ldap
Vulnerability : denial of service
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2007-5794
Debian Bug : 453868
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.
