    ===========================================================
    Ubuntu Security Notice USN-69-1 January 24, 2005
    evolution vulnerability
    CAN-2005-0102
    ===========================================================

    A security issue affects the following Ubuntu releases:

    Ubuntu 4.10 (Warty Warthog)

    The following packages are affected:

    evolution

    The problem can be corrected by upgrading the affected package to
    version 2.0.2-0ubuntu2.1. In general, a standard system upgrade is
    sufficient to effect the necessary changes.

    Details follow:

    Max Vozeler discovered an integer overflow in camel-lock-helper. An
    user-supplied length value was not validated, so that a value of -1
    caused a buffer allocation of 0 bytes; this buffer was then filled by
    an arbitrary amount of user-supplied data.

    A local attacker or a malicious POP3 server could exploit this to
    execute arbitrary code with root privileges (because camel-lock-helper
    is installed as setuid root).
