Hi there,

I see that Debian packages have been patched to correct the two CVE
(1.4.12.1+dfsg-4).

I'd like to know if ubuntu packages could receive the same love !

Thank you.

Thomas.

&gt; The CVEs are incorrect; both issues were fixed in 1.4.14. An official<=
br>
&gt; announcement from <a href=3D"http://openafs.org" target=3D"_blank">ope=
nafs.org</a> about these issues will hopefully be<br>
&gt; available soon.<br>
<br>
</div>For various reasons (none of them to do with Debian), Debian publicis=
ed those CVEs, and their corresponding security release, before we were rea=
dy to publish our advisory. Sadly, we&#39;re now left playing catch up.<br>

<br>
Even more sadly, the text that Debian registered for those CVEs is, as Andr=
ew indicates, incorrect.<br>
<br>
CVE-2011-0430 affects only RX servers using rxkad authentication. This mean=
s fileservers and database servers, but NOT the cache manager. A remote att=
acker may cause such a server to crash. The bug is present from 1.2.8 thru =
1.4.12.1 and 1.5.0 thru 1.5.74<br>

<br>
CVE-2001-0431 is a bug in the Linux cache manager. A local attacker with ac=
cess to the AFS file space may cause the cache manager to oops. This bug is=
 present from 1.4.11 thru 1.4.12.1 and 1.5.61 thru 1.5.74. Note that it is =
rare that kernel bugs which causes oopses result in security advisories. Le=
ft to our own devices, OpenAFS would probably not have issued an advisory f=
or this issue.<br>

<br>
1.4.14 fixes both of these issues.<br>
<br>
Hopefully I&#39;ll get the website updated shortly. In the mean time, if yo=
u would like patches for older versions of OpenAFS, they are available usin=
g the following git SHA1s:<br>
<br>
0430 is fixed by 707a959c96b01506f6d8eacbbf47a872af882626<br>
0431 is fixed by beaf16069ed9a9f3355adfdf5e03b2bb28c21a8a<br>
