CVE-2011-4079: Buffer Overflow
First published: Wed Oct 26 2011(Updated: )
A bug in slapd's UTF8StringNormalize() function can cause a one-byte buffer overflow when it is passed a zero-length string. The code then writes a '\0' past the one-byte long buffer allocated on the heap, which could possibly allow a remote authenticated user to crash slapd. As per the upstream report [1], this bug has been present since 2003-04-07 [2] so should affect all versions of openldap we currently ship. A patch to correct the flaw has been committed [3] (depends on the previous patch [4]).
