The Apache HTTP server is one of the most popular web servers on the
Internet. The Apache module mod_rewrite provides a rule-based engine to
rewrite requested URLs on the fly.
An off-by-one flaw has been found in Apache's mod_rewrite module by
Mark Dowd of McAfee Avert Labs. This flaw is exploitable depending on
the types of rewrite rules being used.
A remote attacker could exploit the flaw to cause a Denial of Service
or execution of arbitrary code. Note that Gentoo Linux is not
vulnerable in the default configuration.
Security is a primary focus of Gentoo Linux and ensuring the
confidentiality and security of our users machines is of utmost
importance to us. Any security concerns should be addressed to
security@gentoo.org or alternatively, you may file a bug at
http://bugs.gentoo.org.
Package : freeciv
Date : July 31, 2006
Affected: 2006.0
Problem Description:
Buffer overflow in Freeciv 2.1.0-beta1 and earlier, and SVN 15 Jul
2006 and earlier, allows remote attackers to cause a denial of service
(crash) and possibly execute arbitrary code via a (1) negative
chunk_length or a (2) large chunk->offset value in a
PACKET_PLAYER_ATTRIBUTE_CHUNK packet in the
generic_handle_player_attribute_chunk function in common/packets.c, and
(3) a large packet->length value in the handle_unit_orders function in
server/unithand.c.
The updated packages have been patched to fix this issue.
Package : kdegraphics
Date : August 1, 2006
Affected: Corporate 3.0
Problem Description:
Tavis Ormandy, Google Security Team, discovered several vulnerabilites
the libtiff image processing library. Older versions of kdegraphics use
an embedded copy of the libtiff code, with possibly the same
vulnerabilities:
Several buffer overflows have been discovered, including a stack
buffer overflow via TIFFFetchShortPair() in tif_dirread.c, which is
used to read two unsigned shorts from the input file. While a bounds
check is performed via CheckDirCount(), no action is taken on the
result allowing a pathological tdir_count to read an arbitrary number
of unsigned shorts onto a stack buffer. (CVE-2006-3459)
A heap overflow vulnerability was discovered in the jpeg decoder,
where TIFFScanLineSize() is documented to return the size in bytes
that a subsequent call to TIFFReadScanline() would write, however the
encoded jpeg stream may disagree with these results and overrun the
buffer with more data than expected. (CVE-2006-3460)
The NeXT RLE decoder was also vulnerable to a heap overflow
vulnerability, where no bounds checking was performed on the result of
certain RLE decoding operations. This was solved by ensuring the
number of pixels written did not exceed the size of the scanline
buffer already prepared. (CVE-2006-3462)
An infinite loop was discovered in EstimateStripByteCounts(), where a
16bit unsigned short was used to iterate over a 32bit unsigned value,
should the unsigned int (td_nstrips) have exceeded USHORT_MAX, the
loop would never terminate and continue forever. (CVE-2006-3463)
Multiple unchecked arithmetic operations were uncovered, including a
number of the range checking operations deisgned to ensure the offsets
specified in tiff directories are legitimate. These can be caused to
wrap for extreme values, bypassing sanity checks. Additionally, a
number of codepaths were uncovered where assertions did not hold true,
resulting in the client application calling abort(). (CVE-2006-3464)
The updated packages have been patched to correct these issues.
Package : libtiff
Date : August 1, 2006
Affected: 2006.0, Corporate 3.0, Multi Network Firewall 2.0

that a subsequent call to TIFFReadScanline() would write, however the
encoded jpeg stream may disagree with these results and overrun the
buffer with more data than expected. (CVE-2006-3460)
Another heap overflow exists in the PixarLog decoder where a run
length encoded data stream may specify a stride that is not an exact
multiple of the number of samples. The result is that on the final
decode operation the destination buffer is overrun, potentially
allowing an attacker to execute arbitrary code. (CVE-2006-3461)
The NeXT RLE decoder was also vulnerable to a heap overflow
vulnerability, where no bounds checking was performed on the result of
certain RLE decoding operations. This was solved by ensuring the
number of pixels written did not exceed the size of the scanline
buffer already prepared. (CVE-2006-3462)

number of codepaths were uncovered where assertions did not hold true,
resulting in the client application calling abort(). (CVE-2006-3464)
A flaw was also uncovered in libtiffs custom tag support, as
documented here http://www.libtiff.org/v3.6.0.html. While well formed
tiff files must have correctly ordered directories, libtiff attempts
to support broken images that do not. However in certain
circumstances, creating anonymous fields prior to merging field
information from codec information can result in recognised fields
with unexpected values. This state results in abnormal behaviour,
crashes, or potentially arbitrary code execution. (CVE-2006-3465)
The updated packages have been patched to correct these issues.

3) Special Instructions and Notes
Please restart all applications using libtiff. Desktop users should logout
and re-login.
On server systems you have to restart all server applications manually.
4) Package Location and Checksums
The preferred method for installing security updates is to use the YaST
Online Update (YOU) tool. YOU detects which updates are required and
automatically performs the necessary steps to verify and install them.
Alternatively, download the update packages for your distribution manually
and verify their integrity by the methods listed in Section 6 of this
announcement. Then install the packages using the command
rpm -Fhv <file.rpm>
to apply the update, replacing <file.rpm> with the filename of the
downloaded RPM package.
5) Pending Vulnerabilities, Solutions, and Work-Arounds:
Please read the weekly summary report.
6) Authenticity Verification and Additional Information
Announcement authenticity verification:
SUSE security announcements are published via mailing lists and on Web
sites. The authenticity and integrity of a SUSE security announcement is
guaranteed by a cryptographic signature in each announcement. All SUSE
security announcements are published with a valid signature.
To verify the signature of the announcement, save it as text into a file
and run the command
gpg --verify <file>
replacing <file> with the name of the file where you saved the
announcement. The output for a valid signature looks like:
gpg: Signature made <DATE> using RSA key ID 3D25D3D9
gpg: Good signature from "SuSE Security Team <security@suse.de>"
where <DATE> is replaced by the date the document was signed.
If the security team's key is not contained in your key ring, you can
import it from the first installation CD. To import the key, use the
command
gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc
Package authenticity verification:
SUSE update packages are available on many mirror FTP servers all over the
world. While this service is considered valuable and important to the free
and open source software community, the authenticity and the integrity of
a package needs to be verified to ensure that it has not been tampered
with.
There are two verification methods that can be used independently from
each other to prove the authenticity of a downloaded file or RPM package:
Using the internal gpg signatures of the rpm package
MD5 checksums as provided in this announcement
The internal rpm package signatures provide an easy way to verify the
authenticity of an RPM package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, replacing <file.rpm> with the
filename of the RPM package downloaded. The package is unmodified if it
contains a valid signature from build@suse.de with the key ID 9C800ACA.
This key is automatically imported into the RPM database (on
RPMv4-based distributions) and the gpg key ring of 'root' during
installation. You can also find it on the first installation CD and at
the end of this announcement.
If you need an alternative means of verification, use the md5sum
command to verify the authenticity of the packages. Execute the command
md5sum <filename.rpm>
after you downloaded the file from a SUSE FTP server or its mirrors.
Then compare the resulting md5sum with the one that is listed in the
SUSE security announcement. Because the announcement containing the
checksums is cryptographically signed (by security@suse.de), the
checksums show proof of the authenticity of the package if the
signature of the announcement is valid. Note that the md5 sums
published in the SUSE Security Announcements are valid for the
respective packages only. Newer versions of these packages cannot be
verified.
SUSE runs two security mailing lists to which any interested party may
subscribe:
The information in this advisory may be distributed or reproduced,
provided that the advisory is not modified in any way. In particular, the
clear text signature should show proof of the authenticity of the text.

After a standard system upgrade you need to restart Firefox to effect
the necessary changes.
Details follow:
USN-327-1 fixed several vulnerabilities in Firefox. Unfortunately the
new version introduced a regression in the handling of streamed media.
Embedded media which were linked with a scheme other than http:// did
not work any more. This update fixes this regression.
