Ubuntu 4.10 : cyrus21-imapd vulnerabilities (USN-31-1)

Ubuntu Security Notice (C) 2004-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

Stefan Esser discovered several buffer overflows in the Cyrus IMAP
server. Due to insufficient checking within the argument parser of the
'partial' and 'fetch' commands, an argument like 'body[p' was detected
as 'body.peek'. This could cause a buffer overflow which could be
exploited to execute arbitrary attacker-supplied code.

This update also fixes an exploitable buffer overflow that could be
triggered in situations when memory allocation fails (i. e. when no
free memory is available any more).

Both vulnerabilities can lead to privilege escalation to root.

Solution :

Update the affected packages.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
