    Sendmail code execution vuln announced (CVE-2006-0058)

    A new race condition affecting versions of Sendmail prior to 8.13.6 has been announced. The risk is it could allow an attacker to execute code.

    US-CERT posting
    Sendmail patch
    RedHat release
    Vulnerability Note VU#834865
    Sendmail contains a race condition
    Overview
    A race condition in Sendmail may allow a remote attacker to execute arbitrary code.
    I. Description
    Sendmail
    Sendmail is a widely used mail transfer agent (MTA).

    Mail Transfer Agents (MTA)

    MTAs are responsible for sending an receiving email messages over the internet. They are also referred to as mail servers or SMTP servers.

    The Problem

    Sendmail contains a race condition caused by the improper handling of asynchronous signals. In particular, by forcing SMTP server to have an I/O timeout at exactly the correct instant, the attacker may be able to execute arbitrary code with the privileges of the Sendmail process.

    More information is available in the Sendmail version 8.13.6 release page and the Sendmail MTA Security Vulnerability Advisory.

    Considerations

    Versions of Sendmail prior to 8.13.6 are affected.


    II. Impact
    A remote, unauthenticated attacker could execute arbitrary code with the privileges of the Sendmail process. If Sendmail is running as root, the attacker could take complete control of an affected system.
    III. Solution
    Upgrade
    This issue is corrected in Sendmail version 8.13.6.

    Patches to correct this issue in Sendmail versions 8.12.11 and 8.13.5 are also available

    Above thread has been merged as the subject matter is duplicated

    If you cannot do someone any good: don't do them any harm....
    As long as you did this to one of these, the least of my little ones............you did it unto Me.

    Hey Hey,

    This is part of the reason why AO is considered to be a "**** hole" by so many.. good, informative, up-to-date news is posted... exactly what should be posted.. and people neg the thread... idiots... and people neg a poster... why... because of the title of his post??? He still posted worthwhile information... it was merged if you read further down.. that's why it was repeated info... The title of his post was originally the title of a thread... sheesh.... this is really sad..

    Anyways I've removed the offending post and boosted the status of this with a few well placed greenies..

    Peace,

    Well, it looks like hell has frozen over, the day has finally come when I agree with HT. j/k!

    That is a major concern of mine. Good threads get screwed because of that very often. Glad to see I am not alone on that one.

    Thanks HT,
