"It was discovered that the SIEVE component of cyrus-imapd and
kolab-cyrus-imapd, the Cyrus mail system, is vulnerable to a buffer
overflow when processing SIEVE scripts. This can be used to elevate
privileges to the cyrus system user. An attacker who is able to
install SIEVE scripts executed by the server is therefore able to read
and modify arbitrary email messages on the system. The update
introduced by DSA 1881-1 was incomplete and the issue has been given
an additional CVE id due to its complexity."
