1) Solved Security Vulnerabilities
To avoid flooding mailing lists with SUSE Security Announcements for minor issues, SUSE Security releases weekly summary reports for the low profile vulnerability fixes. The SUSE Security Summary Reports do not list md5 sums or download URLs like the SUSE Security Announcements that are released for more severe vulnerabilities.
Fixed packages for the following incidents are already available on our FTP server and via the YaST Online Update.
- fetchmail man in the middle attacks Three security issues have been fixed in fetchmail:
CVE-2005-4348: fetchmail when configured for multidrop mode, allows remote attackers to cause a denial of service (application crash) by sending messages without headers from upstream mail servers.
CVE-2006-5867: fetchmail did not properly enforce TLS and may transmit clear-text passwords over unsecured links if certain circumstances occur, which allows remote attackers to obtain sensitive information via man-in-the-middle (MITM) attacks.
CVE-2006-5974: fetchmail when refusing a message delivered via the mda option, allowed remote attackers to cause a denial of service (crash) via unknown vectors that trigger a NULL pointer dereference when calling the ferror or fflush functions.
All SUSE Linux versions containing fetchmail were affected.
- capi4hylafax potential code execution In the capi4hylafax fax suite, by using shell meta characters in the sender number remote attackers could potentially execute arbitrary commands (CVE-2006-3126).
It is not clear if this is exploitable at all.
All SUSE Linux based products containing capi4hylafax were updated.
- squirrelmail cross site scripting problems Multiple cross site scripting bugs in squirrelmail have been fixed (CVE-2006-6142).
SUSE Linux 9.3 up to 10.1 and openSUSE 10.2 are affected by this problem.
- rubygems file overwrite problem This update fixes a vulnerability in rubygems that allowed to overwrite files with root privileges. (CVE-2007-0469)
SUSE Linux 10.0, 10.1 and openSUSE 10.2 are affected by this problem.
- ruby denial of service problem The ruby package was updated to fix a denial of service problem in its CGI module when parsing multipart MIME messages. (CVE-2006-6303)
All products containing ruby were affected by this problem.
- clamav bugfix release 0.90.1 The virus scan engine clamav was brought to version 0.90.1.
This was not a security, but only a bugfix release. The major version of libclamav.so was bumped, so we also released sylpheed-claws and klamav updates to provide consistency. ______________________________________________________________________________
2) Pending Vulnerabilities, Solutions, and Work-Arounds
- Month of PHP Bugs We are following the Month of PHP bugs closely and collect the reported problems. Once the month of bugs is over, we will release updated PHP packages. ______________________________________________________________________________
3) 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 containing 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 firstname.lastname@example.org"
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 integrity of a package needs to be verified to ensure that it has not been tampered with.
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 email@example.com 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 included at the end of this announcement.
- SUSE runs two security mailing lists to which any interested party may subscribe:
firstname.lastname@example.org - General Linux and SUSE security discussion. All SUSE security announcements are sent to this list. To subscribe, send an e-mail to email@example.com.
firstname.lastname@example.org - SUSE's announce-only mailing list. Only SUSE's security announcements are sent to this list. To subscribe, send an e-mail to email@example.com.
