Debian DSA-1893-1 : cyrus-imapd-2.2 kolab-cyrus-imapd - buffer overflow

high Nessus Plugin ID 44758

Language:

Synopsis

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

Description

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.

Solution

Upgrade the cyrus-imapd-2.2 and kolab-cyrus-imapd packages.

For the oldstable distribution (etch), this problem has been fixed in version 2.2.13-10+etch4 for cyrus-imapd-2.2 and version 2.2.13-2+etch2 for kolab-cyrus-imapd.

For the stable distribution (lenny), this problem has been fixed in version 2.2.13-14+lenny3 for cyrus-imapd-2.2, version 2.2.13-5+lenny2 for kolab-cyrus-imapd.
