CVE-2006-5740: An unspecified vulnerability in the LDAP dissector could be used to crash Ethereal. CVE-2006-4574: A single \0 byte heap overflow was fixed in the MIME multipart dissector. Potential of exploitability is unknown, but considered low. CVE-2006-4805: A denial of service problem in the XOT dissector can cause it to take up huge amount of memory and crash ethereal. CVE-2006-5469: The WBXML dissector could be used to crash ethereal. CVE-2006-5468: A NULL pointer dereference in the HTTP dissector could crash ethereal. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes None. 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. x86 Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/ethereal-0.10.14-16.11.i586.rpm 6aecc0deb29a6339f1fa941c65844c6d ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/ethereal-devel-0.10.14-16.11.i586.rpm 4c207d76c0f0ada418b790dadcff33f5 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/ethereal-0.10.13-2.14.i586.rpm 2f904b719bfbed232744856a4f9eca91 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/ethereal-devel-0.10.13-2.14.i586.rpm f6957aa0c03893d7fd47873999aaf5c1 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/ethereal-0.10.13-2.14.i586.rpm 74cf82fc2bc0a400ca64c66d45064847 Power PC Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/ethereal-0.10.14-16.11.ppc.rpm 1c832fcde7f65332e9d0b47274229f69 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/ethereal-devel-0.10.14-16.11.ppc.rpm 7f303f1eeccd68a1eee8057f56807a3f SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/ethereal-0.10.13-2.14.ppc.rpm 542ae786e2cb511767c7a4e6449b80cf ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/ethereal-devel-0.10.13-2.14.ppc.rpm 178014fc85ec3a0ca43ed9b8ed1cdd26 x86-64 Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/ethereal-0.10.14-16.11.x86_64.rpm 30ca5d51e0f3e889b31a59bad4611dfc ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/ethereal-devel-0.10.14-16.11.x86_64.rpm 2990cb62f731d700675a75203bbd5aa7 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/ethereal-0.10.13-2.14.x86_64.rpm 542b66bcc88e07faec6c33abda8f5d7c ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/ethereal-devel-0.10.13-2.14.x86_64.rpm 7a936eff6d66a5574e564c4255e3fa46 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/ethereal-0.10.13-2.14.x86_64.rpm bd6cc27b6b9e05441bacdba249357f5d Sources: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/src/ethereal-0.10.14-16.11.src.rpm b04b4bb194dfbf4ea92b822149bd3664 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/ethereal-0.10.13-2.14.src.rpm ff3b7fd57d84597700a75f95fbfcc3e7 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/ethereal-0.10.13-2.14.src.rpm b53b87038538e026052356b8a89a0f82 Our maintenance customers are notified individually.

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: 1) Using the internal gpg signatures of the rpm package 2) MD5 checksums as provided in this announcement 1) 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. 2) 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: suse-security@suse.com - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-subscribe@suse.com>. suse-security-announce@suse.com - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to <suse-security-announce-subscribe@suse.com>. For general information or the frequently asked questions (FAQ), send mail to <suse-security-info@suse.com> or <suse-security-faq@suse.com>. ===================================================================== SUSE's security contact is <security@suse.com> or <security@suse.de>.
