USN31-1 : cyrus21-imapd vulnerabilities

Vulnerability Assessment Summary
cyrus21-imapd vulnerabilities

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- cyrus21-admin
- cyrus21-clients
- cyrus21-common
- cyrus21-dev
- cyrus21-doc
- cyrus21-imapd
- cyrus21-murder
- cyrus21-pop3d
- libcyrus-imap-perl21

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 :

Upgrade to :
- cyrus21-admin-2.1.16-6ubuntu0.1 (Ubuntu 4.10)
- cyrus21-clients-2.1.16-6ubuntu0.1 (Ubuntu 4.10)
