USN-31-1: cyrus21-imapd vulnerabilities
Posted on: 11/23/2004 05:18 PM

A cyrus21-imapd security update has been released for Ubuntu Linux 4.10

Ubuntu Security Notice USN-31-1 November 23, 2004
cyrus21-imapd vulnerabilities
CAN-2004-1012, CAN-2004-1013,

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog)

The following packages are affected:


The problem can be corrected by upgrading the affected package to version 2.1.16-6ubuntu0.1. In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

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.
