November: the month of kernel bugs
November 15, 2006
This article was contributed by Jake Edge.
A security researcher has proclaimed November to be the 'Month of Kernel
Bugs' (MoKB) and is releasing one bug each day to highlight unreported
issues with various kernels. The
associated web site currently has
six separate Linux bugs listed as well as bugs for MacOS, FreeBSD, Solaris
and Windows. The project was first
announced on the bugtraq
mailing list along with a tool that can fuzz various Linux filesystems.
The Linux bugs described are all filesystem related; they were found using the
fsfuzzer tool to generate various kinds of improperly formatted filesystem
data and to feed it to the Linux filesystem code. This leads to various
kinds of kernel problems, mostly crashes. Bugs have been found in several
different filesystem types: ext2, ext3, iso9660, cramfs, and squashfs.
The vulnerability found for cramfs actually exists in the zlib decompression
code and could potentially lead to arbitrary code execution.
While these bugs are fairly serious, they are also fairly difficult to exploit.
Other than iso9660, it is rare that a Linux user will mount a filesystem
generated by some external, potentially malicious, entity. USB flash drives
might provide a vector for exploiting some of these bugs, but
users are hopefully savvy enough to be wary of mounting them if they do
not know where they came from. Administrators may also remove the ability
for regular users to mount filesystems, especially on sensitive machines
such as servers.
Kernel bugs that allow arbitrary code execution are particularly serious
because they can provide a way to completely take over the system. If an
attacker can convince someone to mount a specially crafted cramfs image,
they may be able to cause all manner of mayhem with that system. Attacks
targeted at a specific person or company would seem to be the biggest
concern as it would be somewhat difficult to use as a vector for a
widespread infection; the logistics of distributing thousands of USB
keychains to create a Linux botnet would be daunting. The money that could
be earned by renting out the botnet, however, might be enough for some,
especially if they could find a way to do it anonymously.
Two of the reported bugs against Windows wireless drivers would seem to be
of little interest to Linux users, but, unfortunately, that is not the case.
As mentioned
here, Ndiswrapper is often used
to provide Linux 'support' for many wireless adapters and, as Dave Jones
points out,
this makes Linux potentially vulnerable as well. It may be that the vendors
release a fix promptly, but until they do, users of those drivers are
vulnerable to attack. And, in any case, propagating a fix in a Windows
network driver to a substantial portion of its users is not a simple thing
to do.
The MoKB announcement mentions the possibility of 'silent fixes' of these
problems; at least so far, that does not seem to be happening. Silent fixes
are ones that fix a security problem, but in some way obfuscate the
security implications of the fix (or, at least, are not accompanied by a
security advisory). Proprietary vendors are well known for
this kind of behavior, but one would hope open source developers are more,
well, open about those kinds of things. The only fix that seems to have
made its way into the kernel so far is for a an ext3/ext4 bug that was
found prior to the MoKB. It was clearly described as a crash in the patch
and the fsfuzzer tool was referenced. It did not specifically mention it
as a security problem, but opinions differ on whether denial of service
that is not caused externally should be considered a security issue.
While the fixes are not silent, they also do not seem to be very high on
anyone's priority list, either. So far, there do not seem to be patches for
any of the MoKB reported issues posted to the linux kernel mailing list.
The zlib inflate issue, with its memory corruption potential, would seem like
one that should be fixed relatively soon even if its exploit potential is low.
So far, MoKB has produced some interesting bugs, especially on other operating
systems. We will be keeping an eye out for any others that might have a
bigger impact on Linux users and for fixes going into the kernel. November
is only half over.

| Description: |
Two flaws were found in the way Firefox/Thunderbird processed certain regular
expressions. A malicious web page/HTML email could crash the browser or
possibly execute arbitrary code as the user running
Firefox/Thunderbird. (CVE-2006-4565, CVE-2006-4566)
A number of flaws were found in Firefox/Thunderbird. A malicious web
page/HTML email could crash the browser or possibly execute arbitrary code
as the user running Firefox/Thunderbird. (CVE-2006-4571)
A flaw was found in the handling of JavaScript timed events. A malicious
web page could crash the browser or possibly execute arbitrary code as the
user running Firefox/Thunderbird. (CVE-2006-4253)
A flaw was found in the Firefox/Thunderbird auto-update verification
system. An attacker who has the ability to spoof a victim's DNS could get
Firefox to download and install malicious code. In order to exploit this
issue an attacker would also need to get a victim to previously accept an
unverifiable certificate. (CVE-2006-4567)
Firefox did not properly prevent a frame in one domain from injecting
content into a sub-frame that belongs to another domain, which facilitates
website spoofing and other attacks (CVE-2006-4568)
Firefox did not load manually opened, blocked popups in the right domain
context, which could lead to cross-site scripting attacks. In order to
exploit this issue an attacker would need to find a site which would frame
their malicious page and convince the user to manually open a blocked
popup. (CVE-2006-4569) |

CVE-2006-4226
|
| Created: | August 25, 2006 |
Updated: | July 30, 2008 |
| Description: |
MySQL 4.1 before 4.1.21 and 5.0 before 5.0.24 allows a local user to access
a table through a previously created MERGE table, even after the user's
privileges are revoked for the original table, which might violate intended
security policy (CVE-2006-4031).
MySQL 4.1 before 4.1.21, 5.0 before 5.0.25, and 5.1 before 5.1.12, when run
on case-sensitive filesystems, allows remote authenticated users to create
or access a database when the database name differs only in case from a
database for which they have permissions (CVE-2006-4226). |

MySQL: logging bypass
| Package(s): | mysql |
CVE #(s): | CVE-2006-0903
|
| Created: | April 4, 2006 |
Updated: | May 21, 2008 |
| Description: |
MySQL 5.0.18 and earlier allows local users to bypass logging mechanisms
via SQL queries that contain the NULL character, which are not properly
handled by the mysql_real_query function. NOTE: this issue was originally
reported for the mysql_query function, but the vendor states that since
mysql_query expects a null character, this is not an issue for mysql_query. |

OpenSSH: denial of service
| Package(s): | openssh |
CVE #(s): | CVE-2006-4925
CVE-2006-5052
|
| Created: | October 6, 2006 |
Updated: | November 15, 2007 |
| Description: |
packet.c in ssh in OpenSSH allows remote attackers to cause a denial of
service (crash) by sending an invalid protocol sequence with
USERAUTH_SUCCESS before NEWKEYS, which causes newkeys[mode] to be NULL.
An unspecified vulnerability in portable OpenSSH before 4.4, when running
on some platforms, allows remote attackers to determine the validity of
usernames via unknown vectors involving a GSSAPI "authentication abort." |

openssl: insufficient signature checking
| Package(s): | openssl |
CVE #(s): | CVE-2006-4339
|
| Created: | September 5, 2006 |
Updated: | November 15, 2006 |
| Description: |
Philip Mackenzie, Marius Schilder, Jason Waddle and Ben Laurie of Google
Security discovered that the OpenSSL library did not sufficiently check the
padding of PKCS #1 v1.5 signatures if the exponent of the public key is 3
(which is widely used for CAs). This could be exploited to forge signatures
without the need of the secret key. |
